Valence Electrons and the Periodic Table
 
16:53
To see all my Chemistry videos, check out http://socratic.org/chemistry Where do electrons live in atoms? They live in energy levels or shells, which are varying distances from the nucleus, and can hold varying numbers of electrons. The most important electrons in an atom are the valence electrons, which are in the outermost energy level or shell. We'll look at how to determine the number of valence electrons in an atom, based on which column it is in on the periodic table.

Electron Configuration
 
10:17
005 - Electron Configuration In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and studying the first ionization energies of different atoms. ANSWERS: Cl - [Ne] 3s^2 3p^5 Ag - [Kr] 4d^10 5s^1 - Did you get [Kr] 5s^2 4d^9? There are a few exceptions to this law. Most of them are found in the f-block metals and they are not of much chemical significance.

How to Find Valence Electrons! (and Total Electrons)
 
09:28
You can find valence electrons with a shortcut using the periodic table, but it’s good to only do that after you understand why the shortcut works, and to do that you have to draw out the full electrons and orbitals for a few different atoms. Valence electrons are just electrons in the last orbital, they are different from core electrons, which are the total number of electrons except the valence.

How to find the number of protons, neutrons and electrons in atoms and ions
 
03:32
http://www.sciencetutorial4u.com Welcome to sciencetutorial4u. I am showing how to find proton, neutron and electron numbers of atom and ions in this video. An atom has mass number and atomic number. Mass number is the number of both proton and neutron whereas the atomic number is the proton number but which is also the number of electron and this is the reason why the atom is said to be neutral. In an ions, the number of proton and neutron is kept constant but the number of electron changes. if it is a positive ions, the number of electron is decreased by the charge number found on the ions and the opposite is done for negative ions i.e. the electron number is increased by the charge found on the negative ions.

SO4 2- Lewis Structure - How to Draw the Lewis Structure for SO4 2- (Sulfate Ion)
 
04:19
A step-by-step explanation of how to draw the SO4 2- Lewis Structure (Sulfate Ion). Get more chemistry help at http://www.thegeoexchange.org/chemistry/bonding/ The SO4 2- Lewis structure is frequently used in general chemistry and a good structure to help you understand why calculating formal charges is important. There are two resonance structures for SO4 2-. In order to decide which is the predominate form of the molecule we'll need to compare the formal charges. For the SO4 2- Lewis structure first count the total number of valence electrons (found on the periodic table) for the SO4 2- molecule. Once we know how many valence electrons there are in SO4 2- we can distribute them around the central atom with the goal of filling the outer shells of each atom. Only use the number of available valence electrons we calculated earlier. Also note that you should put the SO4 2- Lewis structure in brackets with as 2- on the outside to show that it is an ion with a negative two charge.

What's an Ion?
 
06:52
To see all my Chemistry videos, check out http://socratic.org/chemistry Confused about ions? We'll learn the difference between an atom and an ion. Ions are formed because of a net charge on an atom, because the number of protons and electrons do not balance. This means that the atom is no longer electrically neutral, but is a cation or an anion. We also talk about polyatomic ions.

The Lewis structure was named after Gilbert N. Lewis, who introduced it in his 1916 article The Atom and the Molecule.[4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Lewis structures show each atom and its position in the structure of the molecule using its chemical symbol. Lines are drawn between atoms that are bonded to one another (pairs of dots can be used instead of lines). Excess electrons that form lone pairs are represented as pairs of dots, and are placed next to the atoms. Although main group elements of the second period and beyond usually react by gaining, losing, or sharing electrons until they have achieved a valence shell electron configuration with a full octet of (8) electrons, other elements obey different rules. Hydrogen (H) can only form bonds which share just two electrons, while transition metals often conform to a duodectet (12)[5] rule (e.g., compounds such as the permanganate ion)." Wikipedia contributors. "Lewis structure." Wikipedia, The Free Encyclopedia. Wikipedia, The Free Encyclopedia, 8 Jun. 2016. Web. 2 Jul. 2016. —More on Polyatomic Ions | Wiki— "A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit. The prefix poly- means "many," in Greek, but even ions of two atoms are commonly referred to as polyatomic. In older literature, a polyatomic ion is also referred to as a radical, and less commonly, as a radical group. In contemporary usage, the term radical refers to free radicals that are (not necessarily charged) species with an unpaired electron. An example of a polyatomic ion is the hydroxide ion; consisting of one oxygen atom and one hydrogen atom, hydroxide has a charge of −1. Its chemical formula is OH−. An ammonium ion is made up of one nitrogen atom and four hydrogen atoms: it has a charge of +1, and its chemical formula is NH+ 4. Polyatomic ions are often useful in the context of acid-base chemistry or in the formation of salts. A polyatomic ion can often be considered as the conjugate acid/base of a neutral molecule. For example, the conjugate base of sulfuric acid (H2SO4) is the polyatomic hydrogen sulfate anion (HSO− 4). The removal of another hydrogen ion yields the sulfate anion (SO2− 4).

How to Calculate the Formal Charges for OH- (Hydroxide Ion)
 
01:36
In order to calculate the formal charges for OH- we'll use the equation: Formal charge = [# of valence electrons] - [nonbonding val electrons] - [bonding electrons / 2] The number of valence electrons for the atom of interest is found on the Periodic Table. Nonbonding valence electrons are those around the atom of interest that are not involved in chemical bonds (they aren't being shared with another atom). Bonding valence electrons are the ones shared between atoms. We'll divide this number by two. Some things to note about OH- Formal Charges: - Formal charge is different from the oxidation number! - If you can exceed the octet rule for the central atom it's a good idea to check the formal charges. - If we have isomers or resonance -- formal charges will help us determine most stable structure. - The closer the formal charges are to zero the more likely we have the most favorable Lewis structure for the molecule. - We write the formal charges in ().

(-1) Helpful Videos: • Formal Charges: https://youtu.be/vOFAPlq4y_k • Finding Valence Electrons (element): https://youtu.be/x1gdfkvkPTk • Exceptions to the Octet Rule: https://youtu.be/Dkj-SMBLQzM • How to Draw Lewis Structures: https://youtu.be/1ZlnzyHahvo • Practice Lewis Playlist: https://www.youtube.com/playlist?list=PLZR1BGWBaZ1wEg1Z22ksfNo34UUbaFORo Drawing/writing done in InkScape.

PO4 3- Lewis Structure: How to Draw the Lewis Structure for PO43-
 
03:12
A step-by-step explanation of how to draw the PO4 3- Lewis Structure (Phosphate Ion). For the PO4 3- Lewis structure use the periodic table to find the total number of valence electrons for the PO4 3- molecule. Once we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of PO43- there are a total of 32 valence electrons. For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule. Remember, PO4 3- has a negative three charge on the molecule. For the Lewis structure you'll need to have a total charge for the molecule of 3-. Get more chemistry help at http://www.thegeoexchange.org/chemistry/bonding/
