Re: M7 Boron Oxide formula

Boron is in group 3, therefore it has a charge of 3+. Oxygen is in group 6, therefore it has a charge of 2-. In order to find the formula of Boron and Oxygen, the 3+ and 2- charge must cancel out. 6+/6- is the first charge they can both have, therefore to get a charge of 6+ you will need two Boron a...
