On the periodic table, the periods are organized in:

• columns

• 23 sections

• rows

• alphabetical order

On the periodic table, the elements' groups are organized in:

• rows

• 15 sections

• coordinates

• columns

The smallest particles inside an atom are called:

• protons

• electrons

• neutrons

• megatrons

Particles with no charge in an atom are called:

• neutrons

• protons

• electrons

• boringtrons

Several shells around the atom each hold 8 valence electrons, but how many are in the first shell?

• 1

• 2

• 3

• 4

Noble gases are unlikely to form bonds with other elements because:

• they have 8 valence electrons in their outer shell

• they have 6 valence electrons in their outer shell

• they never learned to share in kindergarten

• they are all negatively charged

When two elements share electrons, they form a/an:

• friendly bond

• amorphous bond

• covalent bond

• ignoble bond

Bonds formed between two ions with opposite charges are called:

• ionitastic bonds

• ionic bonds

• covalent bonds

• nebulous bonds

Na has 1 valence electron in its outer shell. Cl has 7. What is formed when they join?

• Na2Cl

• NaCl3

• NaCl

• Na4Cl

Hydrogen has 1 valence electron in its outer shell. Oxygen has 6. What is formed when they join?

• H2O

• H3O

• HO2

• H2O3
