Detailed explanation-1: -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-2: -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, the nucleus of an atom will always have a positive charge.
Detailed explanation-3: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
Detailed explanation-4: -Nuclei are very dense and extremely small. They contain more than 99.9% of the mass of an atom and are ten thousand times smaller than an atom! The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral.
