Detailed explanation-1: -The nucleus (plural, nuclei) is a positively charged region at the center of the atom. It consists of two types of subatomic particles packed tightly together. The particles are protons, which have a positive electric charge, and neutrons, which are neutral in electric charge.

Detailed explanation-2: -The nucleus is a small, dense region at the center of the atom. It consists of positive protons and neutral neutrons, so it has an overall positive charge. The nucleus is just a tiny part of the atom, but it contains virtually all of the atom’s mass.

Detailed explanation-3: -The nucleus is the positively charged centre of an atom and contains most of its mass. It is composed of protons, which have a positive charge, and neutrons, which have no charge.

Detailed explanation-4: -A nucleus of an atom has protons and neutrons. We know that a proton has a charge of +1, while a neutron has no charge, or 0 . Therefore, thenucleus of an atom will always have apositive charge.

Detailed explanation-5: -Every atom contains a very small, dense, central core called the nucleus. Apart from hydrogen, the nucleus of every other atom is made up of particles called protons and neutrons. The nucleus is surrounded by mostly empty space, except for very tiny particles called electrons that orbit the nucleus.
