How many total orbitals are within the 3s, 3p, and<br> energy level?
Nina [5.8K]

The answer for the following question is explained below.

Therefore the total number of orbitals are " 9 ".

Explanation:

Orbital:

An orbital is a mathematical function that describes the wave-like behavior of an electron,electron pair,or the nucleons.

The total number of orbitals present in the 3rd energy level is 9.

Here,

A 3 s subshell has only one orbital.

A 3 p subshell has three orbitals.

A 3 d subshell has five orbitals.

Therefore the total number of orbitals is:

3 s = 1 orbital

3 p = 3 orbitals

3 d = 5 orbitals

total orbitals in 3rd energy level is = 1 + 3 + 5 =9

Therefore the total number of orbitals are " 9 ".

What is the electron configuration for the Co3+ ion?
liq [111]

Answer:

1s2 2s2 2p6 3s2 3p6 3d4 4s2

Explanation:

Cobalt has twenty seven electrons hence Co3+ has twenty four electrons. It has lost three electrons from its valence shell. In filling the orbitals, we keep in mind that the energy of the 4s level is higher than that of the 3s level when a transition metal forms a complex hence the 4s is filled before the 3s level as shown in the answer above.
