The rule that describes why in a chemical reaction atoms will form bonds that help them achieve 8 valence electrons.
Octet Rule

Metals and nonmetals (cations and anions)
What's happening with the electrons in a covalent bond?
They are being shared
The electrons in the outermost energy level of an atom
Valence electrons

Atomic Number
Potassium has 19 protons and 18 electrons. What is its charge?
1+
Electricity
Bond energy is the energy required to break a covalent bond. Which bond lengths will have higher bond energy?
Shorter
Use dots to represent valence electrons

How can you determine the number of energy levels an element will have?
Row #
Positively charged ion
Cation
All salts are ionic compounds. What shape do all salt crytals have?

nonpolar covalent
Where is chemist G.N. Lewis from?
'Merica

Anion
Write the name for CuCl2
If an atom within a covalent bond has a higher electronegativity, what type of covalent bond will form?
Polar covalent bond
How dots are to be placed around the atomic symbol of an atom
one on each side--can't add a second dot until all sides have at least one
"Do you know what Francium is? Because I don't."
"Yea, it's that stuff the wise men gave to Jesus."-Who said this?
Gracie
Which group is known as the "Halogens"?
Group 17
The sodium ion and Neon have identical electron configurations (1s2, 2s2, 2p6). Despite this, why do they still have different chemical and physical properties?
1) sodium ion has a charge, neon does not
2) Sodium has a different number of protons than neon
Write the formula for potassium oxide
K2O
Which has higher electronegativity, F or Li?
F
Triple bond
First person to break a test tube in the chem lab
Gavynn
Which group on the periodic table contains the radioactive elements?
Actinides
To understand how an atom will form an ion, we need to know how many valence electrons it has. How can we do this?
Use the periodic table group number rule OR write out its electron configuration
An ion made of two or more atoms
Polyatomic ion
Name the following covalent compound: P2S5
Diphosphorus Pentasulfide
How are bonds illustrated within a Lewis structure?
Solid lines
USUALLY the first chem lab group to do things correctly and achieve accurate results

1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2, 4p6
If we see the suffixes -ite or -ate, what element will be in that compound?
Oxygen
The theory that predicts some molecular shapes of covalent compounds based on the idea that pairs of valence electrons surrounding an atom repel each other.
VSEPR (valence shell electron pair repulsion) theory
How do you indicate that a Lewis structure is of a polyatomic ion?
Place brackets around the diagram, and write the charge outside of the brackets
USUALLY the chem lab group where everything is chaos and instructions are not followed
Scott, Blake, Jameson, Ben
An isotope of an element has a different number of which subatomic particle?
Neutrons
