MATTER- Anything that has mass and takes up space.
LIQUID- State of matter that has no definite shape and just takes the shape of its container but has definite volume.
GAS- State of matter has no definite shape nor volume.
SOLID- State of matter that has definite shape and volume.
Chemical Change
Physical Change
Solid to Liquid = Melting
Liquid to Solid = Freezing
Liquid to Gas = Vaporization
Gas to Liquid = Sublimation
Gas to Solid = Deposition
Atom- The smallest most foundation part of matter.
Neutrons ( )
Has No Charge
Location: Nucleus
Mass: 1 AMU(Atomic Mass unit)
Protons(+)
Has Positive Charge
Mass:1 AMU(Atomic Mass Unit)
Location: Nucleus
Electrons (-)
Has Negative Charge
Location: Electron Cloud
Mass: 0
Computing the number of Electron, Proton, and Neutron
Atomic Number(Z) - number of protons in the nucleus of each atom.
Z = number of proton = number of electron - Z=p=e
Mass number(A) - total number of protons and neutrons present in the nucleus.
A = number of proton + number of neutron - A=p+n
neutron - difference of number of neutron and number of protons
n = number of A - number of proton - n=A-p
