An atom's electron configuration ends with 3p3. If another atom has nine more electrons, what would be the continuation of the electron configuration? (5 points)

A.)3p64s23d4

B.)03p34s23d7

C.)3p63d44s2

D.)3p33d74s2

Answer:

A.) is the correct answer

Oseni

The continuation of the electronic configuration would be 3p6, 4s2, 3d4

The initial p-orbital (the 3p3) is incompletely filled. Thus, the first thing would be to fill it completely (3p6) so as to obey the orbital-filling rule. This leaves 6 more electrons

After 3p orbital, the next orbitals are 4s, 3d, 4p, 5s, etc.

The 4s orbital will take a maximum of 2 electrons, leaving 4 more electrons.

Next would be the 3d orbital which can take a maximum of 8 electrons, but only 4 electrons are left.

Thus, the electronic configuration would be 3p6, 4s2, 3d4.
