Atomic History
Found that matter can be split or cut into pieces multiple times.
Who is Democritus?
A subatomic particle with a negative charge. It's quantity is determined by atomic number.
What is an electron?
The distance between the outermost energy level and the nucleus of an atom. (Size of an atom)
What is atomic radius?
These represent electrons with a specific spin in orbital notation.
What are arrows?
This type of bond has a relatively large difference in electronegativity values.
What is an ionic bond?
He used the findings of many other scientists to form his own atomic theory.
Who is John Dalton?
This subatomic particle's quantity involves the difference of the atomic mass and atomic number.
What is a neutron?
How much energy is required to discharge an electron.
This type of notation is written in numerical order, not fill order.
What is electron configuration?
This type of bond has almost no difference in electronegativity values.
What is a nonpolar-covalent bond?
They burned a diamond to find that the same gas was produced when burning coal.
Oxygen has 8 of these positively charged subatomic particles in one atom.
What are protons?
The tendency for an atom to attract electrons.
What is electronegativity?
The spaces in orbital notation where you put the arrows.
What are orbitals?
This is the part of a chemical reaction that runs out first, determining the maximum amount of product that can be made.
What is the limiting reactant?
He developed the plum pudding model.
Who is JJ Thompson?
The difference of the expected mass of an atom and the actual mass of an atom.
What is mass defect?
When you start a new one of these, a new main energy level is added.
What is a period?
The letters in orbital or complete electron configuration notation.
What are sublevels?
In a Lewis Dot Structure, these are represented by dots placed around an element.
What are valence electrons?
He said that there are elements yet to be discovered.
Who is Mendeleev?
Often represented by Helium, this particle has an atomic mass of 4.
What is an alpha particle?
This decreases as you move across a period, but spikes up when you start a new period.
What is atomic radius?
The big number in front of the letters in orbital or complete electron configuration notation.
What are main energy levels?
This number tells us the number of atoms that are present for a substance in a chemical equation.
What is the subscript?
