What is a homogenous mixtures

hi

Explanation:

A mixture which has uniform composition throughout its mass is called homogeneous mixture. The word "homo" means "same". For example, when you completely dissolve salt in the water, you form a homogeneous mixture.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
