200

This happens to the atomic radius as you move down a group.

They get larger.

300

This element has the smallest atomic radius.

Helium

400

This happens to the electronegativity as you move across a period. 

It goes up/Increases

500

As atoms get larger, their electronegativities get...

Smaller

Bond Types

100

In these bonds atoms share their electrons

Covalent Bonds

200

These bonds are formed between cations and anions

Ionic Bonds

300

The difference in this atomic property determines the type of bond formed between two atoms.

Electronegativity

400

An electronegativity difference that is greater than 1.7 indicates that the atoms will have this type of bond 

Ionic

500

These are the two types of covalent bonds.

Polar and Nonpolar

Intermolecular Forces

100

There are this many intermolecular forces.

Three

200

These are the weakest intermolecular forces

London Dispersion Forces

300

These intermolecular forces require a molecules to have a hydrogen that is bonded to a Fluorine, Oxygen, or Nitrogen.

Hydrogen Bonds

400

Molecules with a dipole can have these intermolecular forces.

Dipole-Dipole

Hydrogen Bond

500

These are the strongest intermolecular forces

Hydrogen Bonds

Ions/Ionic Compounds

100

This is the name for atoms with an unequal number of protons and electrons

Ions

200

Atoms with more electrons than protons are called...

Anions

300

Ions formed by elements in group 1 will have this charge

1+

400

This is the chemical formula for the compound formed by Na⁺ and Cl^-

NaCl

500

The net charge for an ionic compound

Zero

Covalent Compounds/Molecule Shapes

100

Atoms in covalent molecules share these

Electrons

200

Electrons are shared evenly between atoms in this type of covalent compound

Nonpolar Covalent

300

Bent molecules have these, while linear molecules don't

Lone pairs of electrons

400

Methane has this molecular shape

Tetrahedral

500

These molecular shapes have three bonds

Chemical Reactions

100

This is the name of the molecules that come out of a chemical reaction

Products

200

This type of chemical reaction always produces water and carbon dioxide

Combustion

300

 A + B -> AB  represents this type of chemical reaction

Synthesis

400

CH_4 + O_2 -> CO_2 + H_2O 

Balance this chemical equation

CH_4 + 2O_2 -> CO_2 + 2H_2O 

500

Chemical reactions have to be balanced to show this scientific law 

The law of conservation of mass

Moles/Molar Mass

100

Moles measure this

The amount (number) of something

200

Molar mass has this unit

g/(mol)

300

The molar mass for an element can be found on this

100

These interact with infrared light in the atmosphere

Greenhouse Gasses

200

The amount of this greenhouse gas has greatly increased in the last 100 years, due to human activity

Carbon Dioxide

300

This scale is used to describe the acidity of a solution

pH scale

400

Bases produce this ion when mixed with water

OH^-

500

pH is determined by the concentration of this ion
