Ice turning into water. It changes state from solid to liquid

What is physical change

100

This subatomic particle has a positive charge and is found in the nucleus of an atom.

proton 

100

Name the compound made from chlorine and sodium.

Sodium Chloride

100

the atomic number is equal to the number of these particles in an atom

The number of protons

100

the bonding of metal and non-metal 

What is ionic bond

200
Any change in a chemical composition that forms in a substance.
What is chemical change
200

This particle has no electric charge and is also located in the nucleus of an atom.

neutron 

200

The balanced formula to describe a compound made between potassium and nitrogen. (ie. H2O is "H" two Oh.)

K3N

200
Name of a trend that increases as you go up and to the right in the periodic table. (two possible answers)
Electronegativity and/or ionization energy.
200

what is the bond between metal and non metal 

covalent bond 

300

The bubbling observed when vinegar and baking soda are mixed.

Chemical Change

300

The mass number of an atom is the sum of these two types of particles.

proton and neutron 

300

Name of this compound:

(NH4)2O

Ammonium oxide.

300
The number of electrons that fill all but the first shell (shell is aka orbital or energy level)

8

300
the difference between polar and non polar covalent bonds
What is Bonds are covalent bonds where electrons are shared unequally between atoms for polar covalent. Where electrons are shared equally between atoms for non polar covalent
400

Souring of milk: Bacteria in the milk produce lactic acid

chemical change

400

The name of a charged particle with different numbers of protons and electrons.

Ions

400

The formula of the compound made between magnesium and sulfate.

MgSO4

400
The force of attraction that causes the atomic radius of an atom to decrease as you move up and to the right on the Ptable.

Columbic attraction (or positive to negative)

400
two properties of covalent compounds
What is forms longer bonds because bonds are weaker than ionic bonds and energy is lowered when atom form a covalent bond
500

The sugar dissolves and disperses in water

physical change

500

This is the smallest unit of an element that retains all the properties of that element.

atom 

500

Total numbers of protons and electrons in the polyatomic ion NH4+

Protons=11

Electrons= 10

500
What remains the same as you move down a coulomb in the periodic table?

Number of valence electrons (ion charge also acceptable)

500
the order of increasing strength and length of chemical bonding and what should always go first
What is increasing strength is nonpolar covalent,polar covalent, and ionic. in order of increasing length, ionic, polar covalent and non polar covalent.metals should always go first
