1.	Atomic numbers (Z) of some elements are given here. Write down the number of electron present in the outermost shell of each of them.Element H C Na Cl NZ 1 6 11 17 7Number of electrons in the outermost shell
Answer» H=1, C=4, Na=7, N=5, in general the NUMBER of electrons in the outermost shell of a particular atom. Similarly, chlorine has only seven electrons in its outermost shell, while sodium has just one. EVEN the GROUP 1 elements have just one valence electron as well as group 18 elements.
