Name the Scientist
This Scientist thought atoms are indivisible particles and the shape and texture of atoms varies depending on the type of matter in which they are found.
Democritus
This subatomic particle is the largest
Neutron
Ions that have more protons than electrons have an excess of positive charge and are known as?
Cations
The unique number of protons in the atoms of an element is that element’s
Atomic Number
Convert the given numbers given in standard (or decimal) notation to scientific notation, and the numbers given in scientific notation to standard (or decimal) notation.
3.14 x 100
3.14
This Scientist thought atoms are hard spheres of different sizes and weights, surrounded by heat envelopes.
Dalton
This subatomic particle is not found in the nucleus
Electron
An anion has a negative charge because it has gained?
An electron
The weighted average of the masses of all the naturally occurring isotopes of that element
Average Atomic Mass
Convert the given numbers given in standard (or decimal) notation to scientific notation, and the numbers given in scientific notation to standard (or decimal) notation.
299,792,458
2.99792458 x 108
This Scientist is known for the Plum pudding model, and suggested negatively charged electrons embedded in a positive substance.
Thomson
The quantity of this subatomic particle determines the atom's identity
Proton
Atoms of the same element with differing numbers of neutrons are called?
Isotopes
Number of Protons, Electrons, and Neutrons for a neutral Iron atom
Iron, Fe,
p+ = 26, e- = 26,
n = 56-26 = 30
Convert the given numbers given in standard (or decimal) notation to scientific notation, and the numbers given in scientific notation to standard (or decimal) notation.
0.00218
2.18 x 10-3
This Scientist is known for the Saturnian model, and thought the atom had a massive and positively charged center surrounded by a flat ring of electrons
Nagaoka
This Scientist developed a model that placed electrons in orbits at specific distances from the nucleus.
Bohr
One isotope of Chlorine has 17 protons and 20 neutrons. What is the name of this isotope
Chlorine-37
How would you represents a Magnesium cation that has lost 2 electrons?
Mg2+
Convert the given numbers given in standard (or decimal) notation to scientific notation, and the numbers given in scientific notation to standard (or decimal) notation.
9.81 x 10-2
0.0981
This Scientist is responsible the Nuclear model which had a tiny, but massive, positively charged nucleus surrounded by electrons.
Rutherford
This Scientist developed the Quantum mechanical model, which has oddly shaped, overlapping orbitals to indicate areas of where electrons in different energy levels are likely to be found.
Schrodinger
What is the isotope notation for Phosphorus-31?
31 15 P
See page 59
This Law states that opposite electrical charges attract each other, while the same charges repel each other
The Law of Electrostatic Charges
Convert the given numbers given in standard (or decimal) notation to scientific notation, and the numbers given in scientific notation to standard (or decimal) notation.
