When naming ionic compounds, the ____________ is named first.

When naming ionic compounds, the ____________ is named second.

Where are cations found on the periodic table?

• Metals - groups 1, 2, and middle mystery transition metals

• Nonmetals - groups 14 -18

Where are anions found on the periodic table?

• Metals - groups 1, 2, and middle mystery transition metals

• Nonmetals - groups 14 - 18

Which groups are Type I cations - aka the charge never changes! Select all that apply

• Group 1

• Group 2

• Group 3-12 (transition metals)

• Group 13

Which groups are correctly matched to their charge?

• Group 1 = 1+

• Group 2 = 2+

• Group 13 = 3+

• All the above.

Which groups are correctly matched to their charge?

• Group 15 = 3-

• Group 16 = 2-

• Group 17 = 1-

• All the above.

When writing formulas, do we write a subscript 1? For example, water consists of 2 hydrogens and 1 oxygen, is the formula: H₂O₁?

• Yes!

• NOO!

• You're crazy.

• I'm so lost.

Do you add mono- to the first element in a covalent bond?

• Yes!

• NOO!

• Really, you've lost it.

• Still lost.

Do we include prefixes for ionic compounds?

• Yes!

• NOO!

• This is concerning.

• What are prefixes?
