yes non metal -nonmetal and metal-non metal

Ok so it's ionic

Ionic bonds are usually named with the first element, and end in -ide.

NaCl
Na=sodium
Cl=chlorine
Sodium Chloride

Answer 10

You do not need to specify the charge of Gallium by writing galium III because it is not a transition metal, and only has one charge. However, stuff like mercury, tin, lead have more than one possible charge and are transition metals. They are the only ones that need it.

Answer 11

k so when do we write roman numeral and when do we not?i know that somejust don't need roman numeral can u guys tell me which ones are the one that need roman numeral and which one don't???Cause on the test i wrote gallium III bromide and they my teacher marked it wrong

Answer 12

Like i said above:
When there are transition metals- use Roman numerals because there may be more than one possible charge.
When there are no transition metals, like gallium- Do not use them, because they have only one charge.

Transition metals are that big block in the middle, that group.
