These three subatomic particles are found in all atoms.
What are:
PROTONS
ELECTRONS
NEUTRONS
When atoms form a bond by sharing electrons this type of bond is formed.
What is a:
COVALENT BOND
If a combination of substances can be reversed by physical means it is called this.
What is a:

Non-metals are usually located on this side of the periodic table. (Left or Right)
What is:
RIGHT SIDE
This subatomic particle is positively charged.
What is a:
PROTON
When a chemical bond is formed after an electron is donated from one element to another this type of bond is formed.
What is an:
IONIC BOND
If a combination of substances can be reversed by changing the temperature or pressure, it is called this.
What is a"
SOLUTION
This is a heavy, soft, malleable, metal that appears silvery with a blueish tint. It is represented by the symbol Pb.
What is:
LEAD
If you know an atom's Atomic Number then you know how many of these are in an atom.
What are:
PROTONS
This subatomic particle has a charge but almost no mass.
What is an:
ELECTRON
True or False:
When two or more elements combine to form a molecule, the new molecule will keep the properties of the elements that formed it.
False:
Chemical Bonds create new molecules that do not keep the same properties as the elements that formed them.
(Example: Combining hydrogen and oxygen to form H2O)
In a solution the liquid part of the solution is called this.
SOLVENT
This element is a strong-smelling halogen gas at room temperature. When combined with Sodium it can form table salt.
What is:
CHLORINE
The Halogen Gases in Group 17 of the periodic table like to form Ionic bonds with metals. They have this many open spots for electrons in their outermost shell.
What is:
ONE open spot
If you add the number of Protons in an atom to the number of Neutrons in that atom you will know this value.
What is:
The ATOMIC MASS of an atom.
When substances that have been combined break their bonds to form new molecules it is called this.
What is a:
CHEMICAL REACTION
This part of a solution will be left behind if you allow the liquid to evaporate.
What is the:
