Atomic Theories 1
Proposed the Plum Pudding Model of the Atom
J.J. Thomson
His atomic model can be described by a Gobstopper
Contains a negative charge
Electron
Atomic number of Nickel
28
This subatomic particle does not carry a charge
Neutron
Was an ancient Greek philosopher
Democritus
Proposed the nuclear model of the atom
Ernest Rutherford
Location of protons and neutrons
The nucleus of the atom
Mass number for Carbon-12
12
Represents a weighted average of the atomic masses of the naturally occurring isotopes of an element
Atomic mass
Type of candy/sweet that represents Thomson's Model of the atom
Chocolate chip or blueberry muffin
Describe Rutherford's model of the atom
Protons found in the nucleus and electrons found outside
Charge of the electron
Negative charge
Represents the number of protons and neutrons in the atom
Mass number
Isotopes
Atoms of the same element which have different numbers of neutrons
These models did not contain any protons or neutrons
Democritus and Dalton
His model contains atomic orbital which are regions of probability where the electron can be found
Erwin Schrodinger
These subatomic particles have the same mass
Protons and neutrons
Mass number of an atom which contains 11 protons and 12 neutrons
23
An example of an alkali metal
Either Li, Na, K, Rb, Cs, or Fr
Arrange the following models from the in order of the oldest to the most recent: Dalton, Democritus, Thomson
Democritus, Dalton, Thomson
Arrange the following models from the most recent to the oldest: Rutherford, Schrodinger, Bohr
Schrodinger, Bohr, Rutherford
These subatomic particles have opposite charges
Proton and electron
Atomic number of chlorine-37
17
Was given credit for developing the periodic table
