Question

Part E

Identify the group of elements that corresponds to the following generalized electron configuration: (noble gas]nsº (n - 1)d10np1

Answer 1

Answer: The group of elements that corresponds to the electronic configuration
`\text{[noble gas] }ns^0(n-1)d^(10)np^1` is group 13.

Step-by-step explanation:

Electronic configuration is defined as the representation of electrons in a given atom.

Valence electrons are defined as the electrons present in the outermost shell or the sub-shell having highest value of 'n'.

We are given:

General electronic configuration =
`\text{[noble gas] }ns^0(n-1)d^(10)np^1`

where,

n = principal quantum number and is determines the energy level of the sub-shell

The number of valence electrons in the configuration are = 2 + 1 = 3

And, as the last electron is entering the p-subshell, so the element is a p-block element.

The given electronic configuration is of group 13 elements.

Hence, the group of elements that corresponds to the electronic configuration
`\text{[noble gas] }ns^0(n-1)d^(10)np^1` is group 13.
