How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

Which element would mostly likely have an electron affinity measuring closest to zero

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
