Question

1. compare the relative charge and mass of each subatomic particle.

Explanation:

Protons have a relative charge of +1 and a relative mass of 1. Neutrons have a relative charge of 0 and a relative mass of 1. Electrons have a relative charge of -1 and a relative mass of approximately 1/1836.

Answer:

Protons: charge +1, mass 1; Neutrons: charge 0, mass 1; Electrons: charge -1, mass ≈1/1836.
