Malleable
This is the number we look at to determine how many protons and neutrons we have in an atom.
Atomic Number
This is what we call the number in front of a chemical compound formula.
HINT: ---------> this number 2CO2
This is the number that tells us how many electron shells we need in our atom illustration and is horizontal on the periodic table.
Period Number
What do we call the document that arranges elements in order by atomic number and elements are arranged by similar atomic structure?
Periodic Table
This number tells us how many VALENCE electrons an atom has and is vertical on the periodic table.
Group Number
The amount of mass in a given space is called...
density
Ability to be drawn into wire.
Ductile
This type of material keeps energy (heat or electricity) from easily transferring.
Protons + Neutrons = _________________
*HINT: we round this number and subtract protons from it to determine neutrons
Atomic Mass
A solid that forms out of a solution is called a....
precipitate
In this type of change, you do NOT have a new substance.
physical change
In this type of change, a NEW substance is formed.
Chemical change
ability of a molecule to accept hydrogen atoms

solubility
The number at the bottom of a chemical compound formula.
HINT: CO2 <---- this number
subscript
What do we call the electrons found on the outer most shell of the atom?
Valence Electron
This type of material allows the flow of energy through it.
*HINT: energy in the form of electricity or heat
conductor
Temperature at which a liquid turns to vapor is called the......

This states that matter is neither created nor destroyed.
Law of Conservation of Matter/Mass
Losing electrons when combined with oxygen
oxidation
What is formed from a chemical reaction?
HINT: found to the right of the yield sign
