Where Are Neutrons Located

Introduction to where are neutrons located:
Atom word has been derived from Greek, which means inseparable or indivisible. Actually the Greeks discovered that matter can be divided into tiny sub particles called atoms.An atom consists of three important kinds of subatomic particles – electron, neutron and proton. Some atoms do not have neutrons.The protons and neutrons are found to be grouped together in a central area called the nucleus. The electrons surround the nucleus in the form a cloud. The number of protons is equal to the number of electrons.

 I like to share this convert celsius to fahrenheit equation with you all through my article.

Properties of protons, neutrons and electrons:

Mass: The mass of atom or atomic mass is the total mass of neutrons, protons, and electrons. The mass that of subatomic particles is measured in atomic mass units (amu) called Daltons. One amu (or Dalton) is approximately 1.7 X 10-24g.

The mass of protons and neutrons is approximately 1 amu. The mass of an electron is negligible. The total mass of an atom is mostly due to the mass of protons and neutrons. The mass number is the total number of protons and neutrons.

Charge: Charge is a state in which particles either attract or repel each other. Two particles that have opposite charges such as positive and negative attract each other. Particles that have the same charge, repel each other; they are both either negative or positive.

Atoms are neutral- no charge or the charges cancel each other.

In the nucleus, protons has a positive (+) charge, neutrons have no charge i.e., they are neutral. Electrons has negative charge (-) and move in the region of orbitals more or less the nucleus.The number of the protons is equal to the number of the electrons; therefore the overall charge is zero.

Conclusion to where be neutrons located:


From the discussion, we can conclude that the proton number in an element is invariable or constant but the number of neutrons may vary, so mass number (protons + neutrons) may vary. These types of an element are known as the isotopes.
