Nucleus.
Usually in the nucleus, but they can also exist free.
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
protons and neutrons are located in the atom's nucleus.
Protons and neutrons are located in the nucleus of an atom. The protons have a positive charge, while neutrons have no charge (they are neutral). The nucleus, containing protons and neutrons, is at the center of an atom and is surrounded by electrons.
Neutrons and protons.
Protons and neutrons are located in the nucleus.
Protons and neutrons are located in the nucleus or center of the atom.
Protons and neutrons are located in the nucleus.
The protons and the neutrons are located in the nucleus of an atom.
In an atom protons and neutrons are located in the atomic nucleus.
Protons and Neutrons compose the nucleus of the atom. They are surrounded by a cloud of electrons. If our universe was an atom, the sun would be the nucleus (with protons and neutrons) and the orbiting planets would be the electrons.
All the protons and neutrons are located in the nucleus (center) Protons are positvely charged (red) neutrons are green, electrons are negatively charged and yellow
Protons and neutrons are subatomic particles located in the atomic nucleus.
