Question

Find the neutral atom in the periodic table which has same level of electrons Na+and f- what is this number

Answer 1

Atoms are neutral; they contain the same number of protons as electrons. 

Na (Sodium) has an atomic number 11 so it has 11 electrons.

F (Fluorine) has an atomic number 9 so it has 9 electrons. 

Na+ will have 10 electrons which is shown by Neon (Ne)

F- will have 10 electrons which is shown by Neon (Ne)

Therefore, the possible answer could be Neon (Ne)
