Part 1

Learning Objectives Identify the basic parts of an atom. Describe the charge and location of protons, electrons and neutrons.

What are Atoms? Positively charged protons and uncharged neutrons are bound together in a dense nucleus, while the negatively charged electrons move around the nucleus. Atom – the smallest particle of matter. They make up everything around us.

Parts of an Atom Proton Neutron Electron - + Positively charged protons and uncharged neutrons are bound together in a dense nucleus, while the negatively charged electrons move around the nucleus.

Parts of an Atom - Proton + - Proton – positively (+) charged atomic particles. Located in the nucleus of the atom. Positively charged protons and uncharged neutrons are bound together in a dense nucleus, while the negatively charged electrons move around the nucleus.

Parts of an Atom - Neutron + - Neutron – uncharged (neutral) atomic particles. Located in the nucleus of the atom. Positively charged protons and uncharged neutrons are bound together in a dense nucleus, while the negatively charged electrons move around the nucleus.

Parts of an Atom - Electron + - Electron – negatively (-) charged atomic particles. Located orbiting around the nucleus. Positively charged protons and uncharged neutrons are bound together in a dense nucleus, while the negatively charged electrons move around the nucleus.

- + Charge and Location PROTON Nucleus NEUTRON NONE ELECTRON PARTICLE CHARGE LOCATION PROTON + Nucleus NEUTRON NONE ELECTRON - Outside Nucleus (in motion)

ELEMENTS Elements are only one type of atom

MOLECULES Molecules two or more atoms held together by chemical bonds.

COMPOUNDS Compounds are made up of different types of atoms.

Molecules vs. Compounds All compounds are molecules. Not all molecules are compounds. Molecule Not compound Molecule Compound

Basic Atomic Structure Movie

Atomic Number 6 How many protons (red) are in this nucleus? Atomic number = # of protons in the nucleus of an atom. It identifies the element.

Atomic Mass 12 What is the atomic mass of this atom? Atomic mass = # of protons + neutrons.

Models of C, H, and O Atoms C, H and O are found in all living things. Hydrogen Atom Oxygen Atom Carbon Atom # of electrons = # of protons

Electron Shells Electrons are arranged in energy levels or shells around the nucleus.

Valence Electron Outer Shell Electron from hydrogen Electron from carbon Valence Electron - an electron that can participate in the formation of a chemical bond.

Isotopes Isotope - atoms of the same element that differ in their number of neutrons.
