200
solid, liquid, gas & plasma
What are the 4 states of matter?
200
These subatomic particles determine the type of element.
What are the protons?
200
These act as buffers in the nucleus.
What are neutrons?
200
sum of protons & neutrons in the nucleus?
What is atomic mass?
200
When an atom gives electron to another atom to form a bond.
What is an ionic bond?
300
Its particles move freely and has no fixed shape or volume
What is a gas?
300
This makes up all living and non-living things. 

(Hint: not the name for the smallest particles.)

What is matter?
300

What type of molecule is formed when atoms from two different elements combine. (as opposed to atoms from the same element.)

What is a compound?
300
number of protons (or electrons) in an atom
What is the atomic number?
300
When an ion loses electrons, it becomes this.
What is a cation?
400
Its particles are packed tightly together and has a fixed volume and shape.
What is a solid?
400
This is when matter changes in size, shape or state.
What is a physical change?
400
This is a general term for atoms that have gained or lost electrons.
What is an ion?
400
This shows that elements have the same number of electrons in the outer shell.
What is the group?
400
When an ion gains electrons, it becomes this.
What is an anion?
500
Stars, lightning and fluorescent light are an example of this state of matter.
What is plasma?
500
This is when matter changes from one substance to another.
What is a chemical change?
500
This is the name for atoms that have the same number of protons, but a different number of neutrons.

(It also means "same place")
