Question

Effective nuclear charge of A.Beryllium B.Sodium C.Neon D.Potassium with steps plzz​

Answer 1

Answer:

A. The effective nuclear charge holding a 2s electron to the nucleus is thus nearly +2, about twice the value for lithium, and the 2s electron clouds are drawn closer to the center of the atom. Boron The next element after beryllium is boron.

B. The effective nuclear charge of the sodium atom is 2.2.

C. For neon you should have figured that the electrons in the first energy level would feel a nuclear charge of +10, the full nuclear charge.

D. The effective nuclear charge of potassium is 2.20
