Consider the two electron arrangements for neutral atoms A and B. Which atom is more stable?
A - 1s2, 2s2, 2p6, 3s1
B - 1s2, 2s2, 2p6, 5s1
A
B
indeterminate

Respuesta :

The outer electron of atom B has moved to a higher energy state because (5s1 compared to 3s1. 5 is greater than 3). Therefore, your answer is B.

Answer:

A

Explanation:

because higher energy levels are unstable
