Explanation:
1.The electronegativity of an atom determines how strongly it attracts electrons to itself. The polarity of a bond is affected by the electronegativity values of the two atoms involved in that bond.
3.bonding electrons are when the electron have the same number and the connect,like valence electrons. Non-bonding electrons are only possible when an atom is unstable, no more than 2 electrons or if the atom is an isotope. bonding electron pairs occur in a covalent bond between two atoms.
