Question

The d subshell can hold up to 10 electrons in an atom.
True
False

Answer 1

TRUE

Step-by-step explanation:

Each electronic shell in an atom is composed of subshells, which are denoted by the symbol s, p, d and f. These subshells are represented by the principal quantum number (n) and the azimuthal quantum number (ℓ).

Each subshell can hold a fixed number of electrons, which is equal to (4ℓ + 2) electrons.

For, d subshell the value of ℓ = 2.

Therefore, the maximum number of electrons that a d-orbital can hold = (4ℓ + 2) electrons = (4×2 + 2) electrons = 10 electrons.
