Which of the following accurately pairs the part of an atom to its charge? a. electron—no charge b. proton—no charge c. neutron—positive charge d. electron—negative charge

D: Electron - Negative Charge

Explanation:

Protons have a positive charge, (pro = +)

Neutrons have a negative charge,  (neutral = 0

Electrons have a negative charge.

An element is determent by the number of protons in the atom, the Isotope of an element is determined by the number of neutrons, and the charge of an atom is determined by its electrons, which is equal to the number of protons.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
