Match the scientist to his contribution to the atomic theory. match term definition j. j. thomson a) positively charged nucleus john dalton b) plum pudding model ernest rutherford c) atoms indivisible james chadwick d) discovery of neutrons

Answer is:

J.J. Thomson- B) Plum Pudding Model.

J. J. Thomson discovered the electron in 1897.  

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.  

John Dalton - C) Atoms indivisible.

Dalton stated that atom is matter that can not be divided

Ernest Rutherford - A) Positively charged nucleus.

According to Rutherford model of the atom:

1) Atoms have their charge concentrated in a very small nucleus.

2) Major space in an atom is empty.

3) Atoms nucleus is surrounded by negatively charged particles called electrons.  

4) An atom is electrically neutral.

James Chadwick - D) Discovery of neutrons.

James Chadwick was a British physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932.

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

explanation:

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
