Question

Chlorine forms the chloride ion to bond with many metals. To become a chloride ion with a -1 charge, a chlorine atom must

Answer 1

C) gain one electron.

Explanation:

A chloride ion forms when a chlorine atom gains an electron. An atom is made up of three fundamental particles which are:

• Protons which are the positively charged particles in an atom.
• Electrons which are the negatively charged particles in an atom.
• Neutrons do not carry any charges.

In a neutral atom, the number of protons and electrons are the same.

For an atom to become charged, it must gain or lose electrons.

• When an atom gains electrons, the number of protons is less than the number of electrons and it is negatively charged. Such an atom is called an anion.
• When an atom loses electrons, the number of protons is more and it becomes positively charged. Such an atom is called a cation.

A chlorine atom that has gained an electron is an anion. It is negatively charged.
