Answer:
(a) Each element has a symbol,one or two letters that represent the element much as your initials represent you. The symbol of an element represents one atom of that element. For 14 of the elements, the symbol consists of one letter.
(b) Molecules are two or more atoms chemically joined together. Compounds are two or more different elements joined together chemically. They can either be heteronuclear or homonuclear
(c) refers to atomic mass unit (abbreviated as amu). It is defined as 1/12 the mass of an atom of carbon-12. According to latest IUPAC guidelines, we use the symbol u instead of amu to represent masses of atoms.

Answer:
First I can only answer your first & second question elements are symbolised by their latin versions of name and their first and second word from english names.
b( molecules are formed when a element's atom is interlocked with same element's atom and form same element e.g. Fe2 and compounds are formed when a variety of atom interlocked with different element's atoms and form a different substance's molecule e.g. H2+O
