Answer 1

Answer:

An ion is an atom or group of atoms where the number of electrons is not equal to the number of protons.

Some examples of cations, or positive ions:

• Aluminum - Al 3+

• Barium - Ba 2+

• Bismuth - Bi 3+

• Cadmium - Cd 2+

• Calcium - Ca 2+

A molecular compound  can be defined as a compound where the atoms share electrons through covalent bonds. It is also known as a covalent compound. The covalent bonds are what hold the molecule together. When atoms share electrons, they are able to have a full outer electron shell.
