Chemistry of Life Atoms, atoms, everywhere

Matter Matter is anything with mass and volume

Matter Matter is anything with mass and volume Mass is the amount of matter

Matter Matter is anything with mass and volume Mass is the amount of matter Volume is the amount of space the matter takes up

Matter Matter is made of atoms

Atoms Atoms are made of subatomic particles

Elements Each element has atoms that are alike, but different from other elements

Elements Each element has atoms that are alike, but different from other elements Elements can't be broken down into simpler matter

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

Elements Six elements make up all living things

Elements Six elements make up all living things S, P, O, N, C, H

Compounds Most elements don't exist by themselves

Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds

Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding:

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

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

Covalent Bonds Happen when atoms share electrons

Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements

Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water

Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water Formula: H 2 O

Ionic Bonds Happen when atoms transfer electrons

Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge

Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt

Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt Formula: Na+Cl-
