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

the big number on the bottom of the symbol

What is the mass number

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 name of the vertical column and the horizontal column
What is vertical columns are called groups and horizontal rows are called periods
200

what is the bond between metal and non metal 

covalent bond 

300

Anything that has mass and takes up space.

What is matter

300

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

proton and neutron 

300
The trend of 

What is periodic trend

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

This term refers to atoms of the same element that have different numbers of neutrons.

isotope 

400
four main periodic trends
What is atomic radius, ionization energy, electronegativity, and electron affinity
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

periodic trend explanation and group trend explanation
What is when comparing elements in the same period,compare the effective nuclear charges for periodic trend explanation. For group trend explanation compare the amount of electron shielding occuring in the same group
