Q4:
Why is the formula for sodium chloride , but the formula for magnesium chloride is ?
- AChlorine forms a ion, so it requires two magnesium ions to form an electrically neutral compound.
- BMagnesium forms ions, so it requires one chloride ion to form an electrically neutral compound.
- CChlorine forms ions, so it requires two magnesium ions to form an electrically neutral compound.
- DMagnesium forms ions, so it requires two chloride ions to form an electrically neutral compound.
- EMagnesium forms a ion, so it requires two chloride ions to form an electrically neutral compound.
Q5:
Which of these statements explains why atoms of neon do not form ionic bonds?
- AAtoms of neon have delocalized electrons.
- BAtoms of neon must gain or lose four electrons to form a stable octet in their outer shell.
- CAtoms of neon already have a stable octet in their outer shell.
- DAtoms of neon form dense, metallic structures instead.
- EAtoms of neon share electrons to form covalent structures.
