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

The group of elements that corresponds to the electronic configuration is group 13.

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 =

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 is group 13.

am i too late?

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
