Detailed explanation-1: -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 has virtually all the mass of an atom, and is very dense.
Detailed explanation-2: -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-3: -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-4: -The nucleus consists of protons and neutrons. The positively charged particle within the nucleus of an atom is called a proton.
