Question

write the charge and mass of neutron

Answer 1

Charge of neutron is neutral

Answer 2

Smallest particle of an element which shows all properties of element is called atom.
  Some characteristics of "atoms" are as follows:
 Atom takes part in chemical reactions independently.
 Atom can be divided into a number of sub-atomic particles.
 Fundamental particles of atom are electron, proton and neutron.

CHARACTERISTICS OF ELECTRON

  Charge: It is a negatively charged particle.
 Magnitutide of charge: Charge of electron is 1.6022 x 10-19 Coulomb.
 Mass of electron: Mass of electron is 0.000548597 a.m.u. or 9.1 x 10-31 kg.
 Symbol of electron: Electron is represented by "e".
Location in the atom: Electrons revolve around the nucleus of atom in different circular orbits.

CHARACTERISTICS OF PROTON

  Charge: Proton is a positively charged particle.
 Magnitude of charge: Charge of proton is 1.6022 x 10-19 coulomb.
 Mass of proton: Mass of proton is 1.0072766 a.m.u.or 1.6726 x 10-27 kg.
 Comparative mass: Proton is 1837 times heavier than an electron.
 Position in atom: Protons are present in the nucleus of atom.
