Asked Sep 27, 2019

Determine the identity of the element with the following electron configuration. Enter the symbol of the element.


Expert Answer

Step 1

Electronic configuration represents the distribution of electrons in the orbitals of an atom. Atom comprises of subatomic particles like electrons, protons, and neutrons among which only the number of electrons are considered for electronic configuration. Electrons are filled in such a way that they achieve a high stable configuration.

Also, atomic number in an atom represents the total number of electrons in it.

Step 2

Let A be the element to be identified. Electronic configuration of A is given as:

A = [Xe]6s24f145d106p3

Here, [Xe] is Xenon, a noble gas which has 54 electrons.

Total number of electrons of A = 54 + 2 + 14 + 1...
