Protons are
A
located in the shells.
B
part of the atomic nucleus.
C
negatively charged.
D
uncharged particles.
Explanation: 

Detailed explanation-1: -Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than . 01% of the volume of the atom, but typically contains more than 99.9% of the mass of the atom.

Detailed explanation-2: -Primarily, the atomic structure of matter is made up of protons, electrons and neutrons. The protons and neutrons make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom. The atomic number of an element describes the total number of protons in its nucleus.

Detailed explanation-3: -The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons–the atomic number–are atoms of the same element.

Detailed explanation-4: -Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
