Explanation:
The modern periodic law states that the physical and chemical properties of the elements are periodic functions of their atomic numbers.
To calculate electronegativity, start by going online to find an electronegativity table. You can then assess the quality of a bond between 2 atoms by looking up their electronegativities on the table and subtracting the smaller one from the larger one. If the difference is less than 0.5, the bond is nonpolar covalent.
Protons goes in the blank. the word can be used for both.
