In an atomic model that includes a nucleus, negative charge is
a. concentrated in the center of an atom.
b. spread evenly throughout the nucleus.
c. concentrated at multiple sites in the nucleus.
d. located in the space outside the nucleus.

Answer : The correct option is, (D)

Explanation :

As we know that there are three subatomic particles which are protons, neutrons and electrons.

The protons and the neutrons are located in the center of the nucleus and the electrons are located in the space outside the nucleus.

The protons are positively charged, electrons are negatively charged and the neutrons has no charge.

Hence, in an atomic model that includes a nucleus, negative charge is located in the space outside the nucleus.
