Elements in group 15 through 17, do they do they lend and borrow electrons?

No groups 15 through 17 borrow electrons to fill their octets with 8
groups 1, 2, 13 lend electrons because its easier for them to lose them than gain them and groups 3-12 and 14 can either lend or borrow electrons because they have 4 electrons in their octet and groups 15-18 borrow electrons because its easier for them to borrow them than to lose them

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
