What is Modern Atomic Theory?
Atomic theory is the technological theory of the
nature of matter. The theory states that matter
is made up of small contaminants called atoms. Prior
for this theory, matter was considered to be able to
become divided into any kind of small volume. The word
atom is derived from the Greek atoms, meaning

Democritus was born inВ Abdera, В ThraceВ around
460В BC. His precise contributions will be difficult to
dope from those of his mentorВ Leucippus, as
they are usually mentioned jointly in texts. Their
supposition on atoms, taken from Leucippus, bears a
passing and partial resemblance to the nineteenthcentury understanding of atomic structure which includes led some to view Democritus since more of a man of science
than other Greek philosophers; yet , their ideas
rested upon very different facets. В Largely disregarded in
Chemist Steve Dalton was born September 6,
1766, in Eaglesfield, Britain. In 1803 he
revealed the concept of Dalton's Law of Partial
Stresses. Also in the 1800s, having been the 1st
scientist to clarify the behavior of atoms in
terms of the measurement of weight. Dalton
passed away July twenty six, 1844 in Manchester, Britain.
Ernest Rutherford known as the daddy of
indivisible physics designed the theory pertaining to the
structure of the atom. He employed a rare metal foil
test, observing the scattering of alpha
allergens, and demonstrated for the first time
the existence of the atomic nucleus.
T. J. Thomson
In 1897, Thomson showed thatВ cathode
raysВ were composed of a previously unfamiliar
negatively billed particle, and thus he is
acknowledged with the discovery and identification
of theВ electron; and, in a broader feeling, with
the discovery of the firstВ subatomic molecule.

Democritus thought that almost all matter can be
composed of unseen elements.
David Dalton found out a theory that
subject is simply composed atoms of different
weights and is combined in ratios by weight.
L. J. Thomson discovered electron
using houses of cathode rays.
Albert Einstein, creates exceptional and
basic theories of relativity, and hypothesizes
about the molecule nature of light. This was the
basis of indivisible energy.
Robert Millikan tested the charge
of a sole atom.
Ernest Rutherford created the
theory for the structure of atom.
Neils Bohr developed the Bohr atomic
model, with electrons exploring in orbits around the
nucleus, and chemical substance properties getting determined by
just how many electrons are inside the outer orbits.
Erwin Shrodinger described just how electrons
transfer wave type, and designed the Schrodinger
equation which describes how a quantum express of a
system changes over time.
James Chadwick discovers the neutron
element of the atomic nucleus.
