The amount of experimental data relating to the relative location of protons, neutrons, and electrons in an atom is so vast that it would be difficult to know where to start. It is known that protons and neutrons attract each other by means of the strong nuclear force; without this attraction it would be impossible to have any atom with more than one proton in the nucleus, since protons repel each other. This requires neutrons to be in the nucleus, with the protons, not orbiting the nucleus. When atoms are ionized, we know they lose or gain electrons and not neutrons because they acquire an electric charge. There are thousands of other ways of confirming this.
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.
The particles that make up the core, or nucleus, of an atom are called protons and neutrons. Tiny particles called electrons orbit the nucleus.
Electrons orbit the nucleus. The nucleus is comprised of protons and neutrons.
The nucleus of an atom is made of neutrons and protons. Electrons move around the outside of the nucleus. The number of electrons around an atoms nucleus compared to the number of protons in the nucleus determines the charge of an atom, and the charge of an atom effects the way that an atom reacts with other atoms.
The nucleus has protons and neutrons. Electrons can be found in the shells of an atom.
Protons and neutrons are in the center of an atom in the nucleus. Electrons are dispersed around the nucleus.
Protons and neutrons are located within the nucleus. Electrons are revolving around the nucleus.
Electrons -- in energy levels outside the nucleus. Protons in the nucleus. Neutrons in the nucleus.
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.
Electrons are around the nucleus. Protons and neutrons are in the middle.
The nucleus is made up of protons and neutrons; the electrons form electron shells around the nucleus.
electron - electron cloud protons and neutron- nucleus
Neutrons and protons are placed in the atomic nucleus; electrons move surrounding this nucleus in clouds of electrons.
Neutrons are part of the nucleus itself, and electrons circle the nucleus
Protons and neutrons are situated in the atomic nucleus and the electrons surround this nucleus.
Protons and neutrons are placed in the atomic nucleus; electrons are around the nucleus.
In an atom- the protons and neutrons are in the nucleus(aproximately centre) which makes the middle positively charged. The electrons are around the nucleus. The electrons are attracted to the nucleus because the nucleus is positively charged.
