Predict the reactivity of beryllium compared with magnesium give a reason for your answer use the periodic table

Beryllium metal is relatively unreactive at room temperature, particularly in its massive form. Magnesium is more electropositive than the amphoteric beryllium and reacts more readily with most of the nonmetals.

Explanation:

it takes on an electronical energy

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
