The Answer is B. Isotopes

Answer 2

Different isotopes of an element have different number of neutrons.

Further Explanation

An atom  

• An atom is defined as the smallest particle of an element that can take part in a chemical reaction.
• Atoms are made of energy shells and the inner nucleus.
• It is also made up of subatomic particles, protons and neutrons.

Neutrons  

• They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
• Neutrons are slightly heavier than protons.
• The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.

Protons

• Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
• The number of protons differ from one element to another and thus used as the atomic number of an individual element.
• The nucleus of an atom is positively charged due to the positive charge of the protons.  
• Additionally, protons do not take part in chemical reactions but in nuclear reactions.

Electrons  

• They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
• The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
• Electrons are the only sub-atomic particles that take part in chemical reactions.

Isotopes

• Isotopes are atoms of the same element that have the same mass number but different atomic number.

Mass number;

• Mass number is the sum of the number of protons and neutrons in the nucleus of an atom of an element.
