How do you determine the chemical reactivity for nonmetals by using the periodic table?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent

To calculate the molarity of a solution, you need to know the moles of solute and the
