The table shows the elements in Period 2 of the Periodic Table:
| Li | Be | B | C | N | O | F | Ne |
Identify an element in Period 2 that forms a basic oxide.
Identify an element in Period 2 that forms an acidic oxide.
Calcium and fluorine react together to form calcium fluoride, CaF2\text{CaF}_2CaF2, a compound with ionic bonding. Explain, in terms of electrons, how calcium atoms and fluorine atoms form calcium and fluoride ions in calcium fluoride.
State what is meant by the term ionic bonding.
Explain why calcium fluoride has a high melting point.
Magnesium is extracted from molten magnesium chloride using electrolysis. Calculate the mass, in grams, of magnesium formed when a charge of 15 faradays is passed through molten magnesium chloride. The ionic half-equation for the formation of magnesium is:
Mg2++2e−→Mg \text{Mg}^{2+} + 2\text{e}^- \rightarrow \text{Mg} Mg2++2e−→Mg(Relative atomic mass: Mg=24\text{Mg} = 24Mg=24)
