Atomic Models
The atomic model created by Thomson
What is the Plum-Pudding model.
The three subatomic particles.
What are protons, neutrons, and electrons.
The scientist who came up with a Periodic Table ordered by mass.
Who is Mendeleev
This is the most stable group of elements on the periodic table.
(Name and group number)
What are the noble gasses; group 18
Who discovered the electron?
Who is Thomson
This man created an atomic model with a positively charged nucleus.
Who is Rutherford.
Positively charged particles
What are protons
This is what the modern periodic table is organized by.
What is atomic number, or number of protons.
Each group contains the same number of these.
The scientist that did the Gold Foil experiment.
Who is Rutherford.
Bohr created a model that placed electrons in these.
What are energy levels, or electron shells
The subatomic particles that make up the nucleus
What are protons and neutrons
These are the three main groupings of elements.
What are metals, nonmetals, and metalloids.
This group contains the most active, or unstable, metals. (Name and group number)
What are the alkali metals; group 1
The number of electrons it takes to fill the second electron shell.
What is 8
This atomic model accounts for the probability of where an electron might be located.
What is the Electron Cloud Model.
The electrons located in the outermost energy level, or electron shell.
What are valence electrons
This metallic sub-group is found between group 3 and group 12 on the periodic table.
What are the transition metals.
This is the most reactive group of non-metals. (Name and group number)
What is the Halogen Family; group 17
This element from group 14 helps make up all organic compounds.
What is Carbon.
The number of electrons it takes to fill the fourth electron shell.
What is 32
When the number of neutrons in an atom increases or decreases and the mass changes, the atom remains the same in the form of a(n)...
What is an isotope.
This characteristic of non-metals is the reason why most are gasses.
What is a low boiling point
This "boring" family's atoms all have 3 valence electrons. (Name and group number)
What is the Boron Family; group 13
Atomic mass - number of protons
What is the number of neutrons
