Yall so, to find the charge of an atom you just have - for example- an atom with 8 protons, 8 neutrons, and 8 electrons . The charge would be neutral right? Now if you took away a electron the charge would be positive right? And if you had 7 protons, 8 neutrons, and 8 electrons the charge would be negative? Is that how it works?

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
