Question

Write the complete electronic configuration for the following elements; Al (atomic number 13) Si (atomic number 14) P (atomic number 15)

Answer 1

Answer:

Al-2, 8,3

Si-2, 8,4

P-2, 8,5

Answer 2

Answer:

Al: 2,8,3 Si:2,8,4. P:2,8,5

Hence, for Al, there will be 2 electrons in the first shell, 8 electrons in the second shell and 3 electrons in the 3rd shell.

For Si, there will be 2 electrons in the first shell, 8 in the second and 4 in the third.

For P, there will be 2 electrons in the first shell, 8 in the second shell and 5 in the third shell.
