Isotopes and Periodicity
100
The positively Charged particle in an atom
What is a Proton
100
Atoms are indivisible balls of different masses
What is Dalton's Model
100
This indicates the number of protons in an element
What is the Atomic number
100
These elements are good conductors of heat, and electricity. They are often ductile and Malleable.
What is Metals
100
Isotopes can in the number of these.
What is neutrons
200
The lightest particle in an atom
What is an electron
200
This was the first atomic model to contain electrons
What is Thomson's Atomic Model
200
Rows of elements that correlate with the number of electron shells in an element
What a period
200
These elements have 2 valence electrons and form many compounds often found in rocks or earth.
What is Alkaline Earth Metals
200
This property decreases in size from left to right along a period.
What is atomic radius
300
This element has 16 protons
What is Sulphur
300
This model/notation displays only the chemical symbol of an atom, and its valence electrons
What is Lewis Notation
300
The number by which the periodic table in organized
What is atomic number
300
These elements are found on either side of the "staircase" on the periodic table.
What are Metalloids
300
This isotope has twice as many neutrons as it does protons.
What is Super-heavy Hydrogen
400
This element is a Halogen and has 2 electron shells
What is Fluorine

This representation of an atom in indicates the number of: Protons Neutrons Electrons on each shell
What is the simplified atomic model
400
Elements found to the right of the staircase on the periodic table
What are non-metals
