For a transition metal.

Question 21

When do you write the first element without a prefix and a second element with a prefix?

Covalent bonds

Question 22

When do you do the exponent cross “multiplication” thing?

Answer 22

For ionic bonds when trying to find the formula.

Question 23

For binary compounds, if they’re ionic, how do you name them?

Answer 23

Just the elements names, the second one has to end with “ide”, (if its a transition metal, you need to also write the roman numeral thing).
