Question

non metals form negative ions​

Answer 1

Answer:

it is so because--

Explanation:

Non metals usually have valence electrons more than 4. So , they have a higher tendency to gain electrons than to loose them. It is so because removing 5,6,7 electrons will require an extremely high amount of energy and also the ion formed will have an extremely larger no. of protons than electrons , thus making it highly charged and unstable. Hence non metals accept electrons and since electrons carry negative charge and non metallic ions have more electrons than protons , hence their ions are negative
