In a chemical reaction, would you expect your Neon ion to have a tendency to attract or lose electrons? How many, and why?
Answer :
An atom becomes an ion when it gains or loses electrons. Cations are positively charged ions that form when an atom loses electrons, and anions are negatively charged ions that form when an atom gains electrons.
Since, Atomic Number of Neon is 10
So, Electronic configuration of Neon will be : 2, 8
Neon has 8 valence electrons. It already has a full valence shell so it does not react easily and does not gain or lose any electrons.
In the case of neon, both the first energy level and the second energy levels are full. This means that an approaching electron cannot penetrate either energy level. it has zero electron affinity.
