Question

What is the first quantum number of a 252 electron in phosphorus,

1322s22p3s23p3?
A. n=0
B. n= 3
O
C. n = 1
O D. n = 2

Answer 1

the correct answer is B

Step-by-step explanation:

The quantum numbers are the constants obtained when solving the Schrodinger equation, the first quantum number or principal quantum number (n), can take values ​​from zero to infinity.

This quantum number is placed as a coefficient in the quantum distribution.

In this case for phosphorus, the number is n = 3

the correct answer is B
