what particles are in the nucleus of an atom?
528186
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

The nucleus of an atom is a small dense region at the center of an atom that contains protons and neutrons. Almost all the mass of an atom is located in the nucleus, with a very small contribution from the electron shells.

An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.

Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. ... Neutrons and protons, commonly called nucleons, are bound together in the dense inner core of an atom, the nucleus, where they account for 99.9 percent of the atom's mass.

Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have electrical charges that are equal and opposite.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. ... We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

An atom is composed of a positively-charged nucleus, with a cloud of negatively-charged electrons surrounding it, bound together by electrostatic force. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. ... Most of an atom is empty space.

Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus.

Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. Masses for the three subatomic particles can be expressed in amu (atomic mass units) or grams.

The atomic nucleus consists of nucleons—protons and neutrons. Protons and neutrons are made of quarks and held together by the strong force generated by gluon exchange between quarks.

A nucleus of an atom usually contains protons, which are particles with a positive charge, and neutrons, which are particles that are neutrally charged (no charge). On the other hand, in biology, the nucleus of a cell is many times larger than the nucleus of an atom.

The nucleus of an atom consists of neutrons and protons, which in turn are the manifestation of more elementary particles, called quarks, that are held in association by the nuclear strong force in certain stable combinations of hadrons, called baryons.

Answer and Explanation: The two subatomic particles that make up the nucleus are the proton and the neutron. Technically, these particles are made of even smaller particles...

Answer and Explanation: The two particles in the atom that are equal in number are the protons and electrons. The protons are located in the nucleus along with neutrons.

The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.

Atoms contain protons, neutrons and electrons. The electrons are arranged in shells around the nucleus.
