1
Chemistry of Life Atoms, atoms, everywhere
2
Matter Matter is anything with mass and volume
3
Matter Matter is anything with mass and volume Mass is the amount of matter
4
Matter Matter is anything with mass and volume Mass is the amount of matter Volume is the amount of space the matter takes up
5
Matter Matter is made of atoms
6
Atoms Atoms are made of subatomic particles
7
Atoms Atoms are made of subatomic particles Protons in the nucleus
8
Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus
9
Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus Electrons orbiting outside the nucleus
10
Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus Electrons orbiting outside the nucleus Mostly its empty space!
11
Elements Each element has atoms that are alike, but different from other elements
12
Elements Each element has atoms that are alike, but different from other elements Elements can't be broken down into simpler matter
13
Elements Each element has atoms that are alike, but different from other elements Elements can't be broken down into simpler matter Elements are arranged on the periodic table
14
Elements Six elements make up all living things
15
Elements Six elements make up all living things S, P, O, N, C, H
16
Compounds Most elements don't exist by themselves
17
Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds
18
Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding:
19
Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding: Covalent bonds
20
Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding: Covalent bonds Ionic bonds
21
Covalent Bonds Happen when atoms share electrons
22
Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements
23
Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water
24
Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water Formula: H 2 O
25
Ionic Bonds Happen when atoms transfer electrons
26
Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge
27
Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt
28
Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt Formula: Na+Cl-
