Question

What two particles are found in the nucleus of an atom?

Answer 1

proton and neutron

Explanation:

Protons and neutrons are found in the nucleus of an atom. They make up a majority of the mass of an atom. In fact, the mass number of an element is the sum of its protons and neutrons.

Since protons have a positive charge and neutrons are neutral, the nucleus of an atom is electrically positive. Rutherford discovered this in his gold foil experiment. He also concluded that the atom is mostly empty space.

Electrons, on the other hand, are found outside of the nucleus in probable locations called orbitals. Electrons are negatively charged and have hardly any mass compared to a proton and a neutron.
