Question

give reasons- 1. an atom is electrically neutral. 2. noble gas show least reactivity. 3. ions are more stable than atoms.

Answer 1

1.Yeah Atoms are electrically nuetral because there are same number of electrons and protons which have positive and negative charges.

2.Noble gas show least reactivity because they are stable naturally.So they donot react and borrow electrons from other atoms.

3.Yeah Ions are more stable than atoms.Because Ions are the charged atoms which have already got stable electronic configuration.
