(b)(i) Give one similarity between a sulfur atom and a sulfur molecule.
Both are made up solely of sulfur.
(ii)
Give one difference between a sulfur atom and a sulfur molecule.
The sulfur atom is a single atom. The sulfur molecule, however, is made up of more than one
sulfur atom.
(c)(i) Give one similarity between a sulfur molecule and a sulfur dioxide molecule.
Both molecules are made up of more than one atom./Both molecules contain sulfur atoms.
(ii)
Give one difference between a sulfur molecule and a sulfur dioxide molecule.
The sulfur molecule is made up of one type of atom while the sulfur dioxide molecule is made up
of more than one type of atom.
