The protons and the neutrons.
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
It is not the sum of two things, but only the number of protons found in the nucleus of the atom. The atomic mass is the total number of neutrons and protons in the nucleus.
The center of an atom is made up of two particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no charge. Together, they make up the nucleus of an atom.
Protons and neutrons compose the nucleus of an atom. Most of the mass of an atom exists in the nucleus. Other smaller sub atomic particles such as quarks exist, but are usually not addressed until advanced physics or chemistry classes.
The nucleus of a helium atom is identical to an alpha particle, which consists of two protons and two neutrons.
There're two particles in the atom nucleus (protons and neutrons)
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
Protons and neutrons.
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
The nucleus of a helium atom contains two protons and two neutrons.
Protons and Neutrons
its proton and its nucleus will have two protons so its electron and atom
The two particles that make up the nucleus of an atom are the proton and the neutron. The proton has a positive charge, and the neutron doesn't have a charge.

The center of an atom is made up of two particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no charge. Together, they make up the nucleus of an atom.
The particles of the atom in the nucleus are the protons and neutrons. Protons carry a positive charge and neutrons have no charge. These two make up the vast majority of an atom's mass. Electrons, with their negative charges, orbit the nucleus in different energy levels.
The number of nucleons in an atom can vary. A nucleon is either of the two components that make up an atomic nucleus. That's either a proton or a neutron. Different atoms have different numbers of nucleons, and even different atoms of a given element can have different numbers of nucleons (because of isotopic variation). Let's look an a couple of examples to make our point.In hydrogen-1, which is the simplest and most common form of hydrogen, there is one proton in the nucleus of the atom. It has 1 nucleon. In hydrogen-2, there are a proton and a neutron in the nucleus, and that's 2 nucleons. In hydrogen-3, there are a proton and two neutrons in that nucleus, and that's 3 nucleons. In helium-3, there are two protons and a neutron in the nucleus, and that's 3 nucleons. You can see what's happening if you think it through.
