Question

If an atom has two protons, three electrons and two neutrons what is the charge of the
atom?

Answer 1

Answer:

This helium atom, it contains 2 electrons in the first place, right?

Gains three electrons: +3(-1) charge.

-3+3=0

It needs +3 charge to neutralise its charge.

I really hope you didn’t mean that a nucleus, preferably of 1 or 2 neutrons accompanying, with 2 protons gains 3 electrons, as the nucleus isn’t neutral in the first place. In this case, you get a helium ion of -1 charge, requiring +1 charge to neutralise its charge.

This is terribly unrealistic, though, as helium has the highest electron affinity out of all the elements.

Answer 2

Answer:

helium

hope this helps uh ✌
