Question

which subatomic particles are found in the nucleus of a hydrogen (h) atom?
a protons and neutrons
b only neutrons
c protons and electrons
d neutrons and electrons

Explanation:

In a basic atom (like hydrogen), the nucleus contains protons and neutrons (except for hydrogen - 1 which has no neutron, but generally, atomic nuclei have protons and neutrons). Electrons are outside the nucleus in the electron cloud. So the subatomic particles found in the nucleus of a basic atom are protons and neutrons.

Answer:

A. protons and neutrons
