A) have same number of electrons and neutrons B) have same number of electrons and protons
C) have same number of protons and neutrons D) have same number of protons, electrons and neutrons
 
Answer & Explanation Answer: B) have same number of electrons and protons

Explanation:

Atoms are composed of three main particles called electrons, protons and neutrons. We know that, the electrons are negatively charged particles whereas protons are positively charged and neutrons have no charge.

 

Hence, as the number of electrons and protons are equal and they are oppositely charged, the atom will have no charge as their charges cancel each other.
