Answer:

d. Electrons have a negative charge and are lighter than protons

Explanation:

The best statement that describes electrons is that electrons are negatively charged and are lighter than protons.

There are three known subatomic particles which are:

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

The mass of the protons and neutrons are similar.

Electrons are lighter than both protons and neutrons.
