Protons are positive, electrons are neutral, neutrons are negative

The atomic mass of an atom is equal to

number of protons plus number of neutrons

number of protons plus number of electrons

number of electrons plus the number of neutrons

What were J. J. Thomson's three contributions to the atomic theory?

Used the cathode ray tube in his discovery

Created the "plum pudding" model of the atom

Discovered the nucleus -did the gold foil experiment

Created a model of the atom with electrons moving around the nucleus in fixed orbits

What were John Dalton three contributions to atomic history?

Believed that atoms of a given element are identical

Hypothesized that the atom is a tiny, hard sphere

Discovered that the atom is mostly empty space

Believed that the universe was made of tiny "uncuttable" particles

What is Neils Bohr's contribution to the atomic theory?

Created a model of the atom with electrons moving around the nucleus in a fixed orbits

Discovered that the proton had a positive charge

Believed that atoms of a given element are identical

What were Ernest Rutherford's three contributions to atomic theory?

Discovered that the atom is mostly empty space

Discovered the nucleus- did the gold foil experiment

Discovered that the proton had a positive charge

Used the cathode ray tube in his discovery

atoms with a positive or negative charge

atoms with ONLY a positive charge

atoms with ONLY a negative charge

An element has three isotopes. Given the abundances and relative masses, calculate the average atomic mass and determine (from the periodic table) which element it is. Abundances | Relative masses 0.005% | 234.04 amu 0.720% | 235.04 amu 99.275% | 238.05 amu

Uranium (#92, Atomic Mass: 238.03 amu)

Fluorine (#9, Atomic Mass: 19.00 amu)

Mercury (#89, Atomic Mass: 200.59 amu)
