Question

Which is the correct order of increasing energy of the listed orbitals in the atom of titanium? (At. no. Z = 22)

3s 3p 3d 4s
3s 3p 4s 3d
3s 4s 3p 3d
4s 3s 3p 3d

Answer 1

Heya,

T(22) = 1s2 2s2 2p6 3s2 3p6 4s2 3d2

Order of energy is 3s 3p 4s 3d.

So, the option (2) is correct.

Hope this helps....:)

Answer 2

The correct order of increasing energy in the atom of titanium is

3s 3p 4s 3d.

Explanation:

• To identify the correct order of increasing energy, an electronic configuration of titanium is required.
• To write it, the number of electrons present in Titanium must be known.
• We know that the atomic number represents the total number of electrons present in it.
• As the atomic number of Titanium is 22, it has 22 electrons. So the electronic configuration of titanium is $1s^22s^22p^63s^23p^64s^23d^2.$
• As $1s^22s^22p^63s^23p^6$ is electronic configuration of Nobel gas argon, it can be represented as$[Ar]3d^24s^2$.
• From the electronic configuration, it is inferred that the correct order of increasing energy in the atom of titanium is 3s 3p 4s 3d.
