The electronic configuration of selenium is

Explanation:

Electronic configuration is the representation of electrons that are present in an element.

Selenium is the element which is present in Group 16 and has an atomic number of 34.

Atomic number is defined as the number of protons or number of electrons present in an atom.

The number of electrons present in this element is 34.

So, the electronic configuration of selenium =

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
