X is an element with the following properties: • melts at -220°C and boils at -188°C;
does not conduct electricity at room temperature:
forms molecular compounds with non-metals;
forms ionic salts with metals in which its ion has a 1-charge.
Would you expect X to be a solid, a liquid or a gas at 20°C? IS
