Properties of a Solid
Regular/Closely packed, Can't flow, Vibrate slightly, Fixed shape/volume, Cannot be compressed
1 of 21
Properties of a Liquid
Irregular/Quite closely packed, Flows to fit the shape of its container, Vibrates slightly more than a solid, Less dense than solids
2 of 21
Properties of a Gas
Very irregular, Very far apart, Moves fast, Not dense, Can be compressed
3 of 21
SOLID into a GAS
Sublimation
4 of 21
GAS into a SOLID
Deposition
5 of 21
Definition of Diffusion
particles move from an area of high concentration to an area of low concentration, without any external force. Happens in liquids + gases, Eventually, the particles are spread evenly throughout the ai
6 of 21
Elements
made up of 1 type of atom
7 of 21
Compounds
made up of 2 more different types of atoms chemically bound together
8 of 21
Mixtures
made up of 2 or more different types of atoms NOT chemically bound together
9 of 21
Protons (Charge, Relative Mass, Location)
+1, 1, Nucleus
10 of 21
Neutrons (Charge, Relative Mass, Location)
0, 1, Nucleus
11 of 21
Electrons (Charge, Relative Mass, Location)
-1, 0, Orbiting the nucleus in shells
12 of 21
Why are atoms neutral?
Because they contain the same number of protons as electrons
13 of 21
Mass No. - Atomic No. =
Neutrons!
14 of 21
What is the number at the top of an element box?
Mass Number
15 of 21
What is the number at the bottom of an element box?
Atomic Number
16 of 21
What is the group number?
number of electrons in the outer shell
17 of 21
What is the period number?
number of shells
18 of 21
ISOTOPES
atoms of the same element with the same number of protons but different number of neutrons. Same atomic no., different mass no. Same chemical properties, Different physical properties
19 of 21
IONS
an atom or a group of atom with a charge
20 of 21
NOBLE GASES
do not react, full outer shells, don't lose/gain electrons
