Define an electron.And briefly describes its properties.
Answers
Answer:
An electron is a stable negatively charged component of an atom. Electrons exist outside of and surrounding the atom nucleus. Each electron carries one unit of negative charge (1.602 x 10-19 coulomb) and has a small mass as compared with that of a neutron or proton.
Electrons have three fundamental properties: charge, mass, and spin. By definition, the electric charge on an electron is −1. The mass of an electron has been measured and found to be 9.109389 × 10 −31 kilograms. Electrons also spin on their axes in much the same way that planets do...
Answer:
J.J Thomson discovered the electrons.
Electron are the type of subatomic particles with negative charge. It's charge is (-1.6×10^-19C) .
Mass of electron is (9.1×10^-31).
Electron revolves around the nucleus.
how are electrons distributed in different orbits (shells)?
the distribution of electron into different orbits of an atom was suggested by bohr and bury.
the following rules are followed for writing the number of electrons in different energy level or shell:
1.the maximum number of electrons present in a shell is given by the formula to 2n^2 where n is the orbit number or energy level index 123 .........
hence. the maximum number of electrons in different shell are as follows: K shell will be =2
L shell will be 4
M shell will be 18
N shell will be 32
2. the maximum number of electrons that can be accommodated in the outermost orbit is
3.electrons are not regulated in a given shall unless the inner shells are filled that is the shell of in a stepwise manner
