Question

Hg has two eletrons in the outer shell .so how it's valancy becoms 1?

Answer 1

Answer:

Electron cover (: Electron Orbital) is the orbit of an electron revolving in the orbit of an atom. These can be thought of as one of the veils over the one located on the side of the navel. Only a certain number of electrons can be present in each shell, so each shell is associated with a specific electron energy. Each cover must be filled with electrons before it starts filling the next one.

The electrons present in the outermost shell determine the properties of that element and are called valence electrons.
