The term Homoatomic is used when the bond is formed between two same atoms or elements of the periodic table. Required fields are marked *. After connecting each outer atom to the central atom, count the number of valence electrons used in the above structure. Nitrogen is an element of the periodic table which is discovered by Daniel Rutherford in 1772. Here, it is important to understand that two valence electrons will be donated by the magnesium atom and one will be received by each fluorine atom. Therefore N2 does not have polar bonds. Explain why? (2 0 4/2) = 0 formal charge on the beryllium central atom. As both are identical atoms, nitrogen atoms, they have the same value of electronegativity.
