NUETRONS
The Neutron is a subatomic particles which
has a symbol (n) or (n0).The neutron have a
neutral charge. They aren't positive like
protons. They aren't negative like
electrons. A British physicist Ernest
Rutherford discovered the atom in 1911
. He constructed a model showing an atom
with a nucleus containing protons and electrons
. Scientists studying the model knew that
something must be missing from it.
Rutherford suggested that some sort of
neutral particle might exist in the nucleus.
Neutrons bind with the protons in the
nucleus, and are stable there.
Electrons
Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The electron core of an atom, consisting of protons and (usually) neutrons. The electron is almost 1,000 times smaller than the mass of a proton. n 1838, British physicist and chemist Michael Faraday (1791-1867) was working with a set of electrodes—metal plates used to emit or collect electric charge—which he had placed at either end of an evacuated glass tube. He applied a charge of several thousand volts between the electrodes, and discovered that an electric current flowed between them.
protons
A positively particle that is a fundamental constituent to fall atomic nuclei .It is the lightest and most stable baryon,having a charge equal in magnitude to that of the electron, Protons carry a positive electric charge. When a single proton captures an electron it makes a hydrogen atom. These protons and neutrons are held so tight in the nucleus by the nuclear force which is the largest force observed so far. Protons with its positive charge keeps electrons go around the nucleus. The proton was discovered (1919) by Ernest Rutherford the nucleus of the lightest isotope of hydrogen the...
