Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on.

You can predict the charge of an ion by looking at its group number on the periodic table. Groups IA, IIA and IIIA all lose electrons and become positively charged. Groups VA, VIA and VIIA all gain electrons and become negatively charged.

Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite.

Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.

Deuteron, nucleus of deuterium (heavy hydrogen) that consists of one proton and one neutron. Deuterons are formed chiefly by ionizing deuterium (stripping the single electron away from the atom) and are used as projectiles to produce nuclear reactions after accumulating high energies in particle accelerators.

An atom has three basic parts – protons, neutrons and electrons.

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

What Are The 5 Parts Of An Atom

• Protons.
• Neutrons.
• electrons.

Atoms are the basic building blocks of ordinary matter. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons ‘orbit’ the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.

Oxygen has eight protons in its nucleus, and therefore eight electrons. The innermost shell of an atom can have only two electrons. So, here, there six electrons in the outer shell—two short of completion (eight total).

Atoms are always neutral in nature. Atoms consist of three basic particles, protons, electrons, and neutrons. The nucleus (center) of an atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and they contain the electrons.
