Which rule is used when writing the name of an ionic bass

Use the helium-4 isotope to define atomic number and mass number. why does knowledge of atomic number enable us to deduce the number of electrons present in an atom

Describe the difference between an ionic and a covalent bond

Ice (H2O) melting at 273 K and 1 atm has = 6.01 kJ/mol and = 6.01 kJ/mol while water vaporizing under the same conditions has = 37.6 kJ/mol and = 40.7 kJ/mol. Why is there such a large difference between and, but not for and?
