1 Atoms, Elements, Compounds, and Ions Atom basic building block of all matter Element Substance that consists of only one type of atom. Molecule has two different atoms. Compound substance that consists of more than one type of element. Ion substance that has a positive or negative charge

2 Atoms have: A nucleus small, heavy part of the atom An electron cloud large, lightweight part of the atom Nucleus Electron Cloud

3 Nucleus of an Atom Nucleus contains: N Protons Have a positive charge All atoms are distinguished by the number of protons it has (atomic number) Neutrons Have no charge Have same mass as protons N N

4 e-e- e-e- Electron Cloud of an Atom An electron cloud contains: Electrons determine bonding properties of substance have a very small mass compared to protons and neutrons orbit the nucleus of the atom are contained within shells of the electron cloud have a negative charge

5 Atom Structure +1 Electron Proton Neutron +1

6 Elements Elements contain one or more of the same type of atom! Examples include: Oxygen – 8 protons per atom Copper – 29 protons per atom Gold – 79 protons per atom Carbon – 6 protons per atom Hydrogen – 1 proton per atom

7 Compounds contain more than one type of atom! Example of organic compound (a compound with carbon atoms): Example of inorganic compound (a compound with no carbon atoms): Carbon Dioxide – CO 2 (1 atom of carbon and two atoms of oxygen) Water – H 2 O (2 atoms of hydrogen and one atom of oxygen)

8 + - An ion is an atom or group of atoms with a positive or negative charge!! A particle with a neutral charge has the same number of protons and electrons. An ion does not have the same number of electrons and protons. He + - A helium atom that is missing one electron. The atom has one more proton than electron, and must have a positive charge. CO Carbonate has two more electrons than protons Examples of ions:

17 This is a Proton. Positive Charge weighs ONE Tells what type of atom it is GIRL

18 This is a Proton. Positive Charge weighs ONE Tells what type of atom it is GIRL

19 This is a Proton. Positive Charge weighs ONE Tells what type of atom it is GIRL

20 This is a Proton. Positive Charge weighs ONE Tells what type of atom it is GIRL This is a Neutron No Charge, Weighs One NUN (does not date)

21 This is a Proton. Positive Charge weighs ONE Tells what type of atom it is GIRL This is a Neutron No Charge, Weighs ONE NUN (does not date) This is an Electron No Weight Negative charge BOY
