Which way does Atomic radius increase? Decrease?
The attractions between the nucleus of one atom with the electron of another.
What are Chemical Bonds?
Used to determine the average atomic mass.
What is Mass Spec. data is used to determine?
What is Carbon?
The molar mass of 4.0 g Sucrose (C₁₂H₂₂O₁₁)!
4.0 g Sucrose x 1 mol Sucrose/342.34 g Sucrose
--> 0.012 Mol Sucrose
INCREASES as you move to the right of the table!
DECREASES as you move down table!
Which way does Ionization energy increase? Decrease?
Transferring electrons (usually involves metal and nonmetal)
What are Ionic Bonds?
Mass Spec. - Technique used to identify the isotopes of element and their relative abundance in nature.
What is Mass Spec.?

Ability of an atom in a molecule to attract shared electrons to itself.
What is Electronegativity?
Sharing electrons (usually two non-metals).
What are Covalent Bonds?
(Mass on x-axis) x (% abundance)
--> Add each result
What is the formula for finding the average atomic mass of an element using a Mass Spec. table?
Element with the Atomic Number of 26!
The molar mass of 69.0 g of Acetic Acid (CH₃COOH)!
69.0 g Acetic Acid x 1 mol Acetic Acid/60.052 g Acetic Acid --> 1.1490042 or 1.1 Mol Acetic Acid (2 SF)
Energy change when atom gains electrons to form negatively charged ion can be endothermic (gains energy) or exothermic (loses energy).
What is Electron Affinity?
Atoms of comparable radii (closer in value).
What are Substantial Alloys?
Variants of an element.
Element with the Atomic Number of 36!
What is Krypton?
In chemistry, the molar mass of a chemical compound is defined as the ratio between the mass and the amount of substance of any sample of the compound. The molar mass is a bulk, not molecular, property of a substance.

Which way does Electron Affinity increase? Decrease?
Atoms of different radii (further in value).
What are Interstitial Alloys?
Carbon-12; Carbon-13; Carbon-14
