What is the charge of the nucleus of an atom?
2 Answers. The nucleus of an atom is constituted only by nucleons that can be protons or neutrons, in a number that is reported by the periodic table. Now, the charge of protons is always positive, the neutrons have no net charge (charge zero) then the total resulting charge of nucleus is positive, due only to the protons contribute. Nam D.
What is the basic structure of an atom?
Atomic Structure. An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
What is the difference between a proton and a neutron?
The nucleus of an atom contains protons and neutrons. Protons and neutrons have nearly equal masses, but they differ in charge. A neutron has no charge, whereas a proton has a positive charge that exactly balances the negative charge on an electron.
What is the mass of an atom expressed in atomic mass units?
Table 1 lists the charges of these three fundamental particles, and gives their masses expressed in atomic mass units. The atomic mass unit (amu) is defined as exactly one-twelfth the mass of a carbon atom that has six protons and six neutrons in its nucleus.

The charge of the nucleus of an atom is the sum of the number of protonsin the ,atom’s nucleus and it is a positive charge. An atom consists of a positively charged nucleussurrounded by one or more negatively chargedparticles called electrons.
What particle has a positive charge in an atom?
Proton has positive charge and is in nucleus of an atom. Neutron has zero charge and is also found in nucleus of an atom. Electron has negative charge and is found in cloud around the nucleus (electron cloud). What is the particles in an atom with no charge?
What is the composition of the nucleus of an atom?
Composition of Nucleus of an Atom The nucleus of an atom consists of proper and tightly arrangement of protons and neutrons. These are the two solid particles in an atom, and consequently, 99.9% of the mass is gathered in the nucleus. Of the two, the protons have a net positive charge.
What is the charge of a neutron?
Neutrons are neutral, and protons have a positive charge. Protons would tend to separate from each other, but a strong force holds them together. The nuclear force that holds nucleons together is the energy obtained in nuclear fusion reactions.
