100
Most of the atom's volume (density) is located here.
What is the electron cloud?
200
It has a positive charge and found in the nucleus of an atom.
What is a proton?
200
This is needed in order for elements to change from state to another. Be specific.
What is a gain or loss of energy?
200
The father of the periodic table
Who is Dmitri Mendeleev?
200
These are highly reactive elements found in group 17 that readily form compounds by gaining one electron to complete their outermost energy level
What are the halogens ?
200
The period number on the periodic table tells you this
The number of energy levels an element has
300
Where the mass of an atom is concentrated.
What is a nucleus?
300
It is one of 2 elements on the periodic table that is a liquid at room temperature. ( Mercury is one).
What is Bromine?
300
This can reveal the number of valence electrons

400
These elements form the largest section of the periodic table (be specific!)
What are the transition metals?
400
Atoms with the same number of protons but different number of neutrons.
What are isotopes?
500
Refers to the outermost electrons in the electron cloud.
What are valence electrons?
500
It is the element that all living things are made of and it forms its own branch of chemistry.
What is carbon?
500
It is the reason the noble gases do not easily form compounds
