Nucleus
• Center of the atom. • Makes majority of the atom’s mass.• Made of Protons and Neutrons.

Protons
• Part of the nucleus• Have positive (+) charge• Protons are the atomic number on the PT• Protons = number of electrons

Neutrons• Part of the nucleus• Have neutral charge• Varying neutrons make isotopes• Find neutrons - Atomic Mass – Atomic
Number (protons) = Neutrons

Mass Number
• Part of the nucleus• Number of protons + neutrons

Isotopes• Atoms with the same number of protons
but different numbers on neutrons• So you can change the number of
neutrons and the element still maintains its identity
• Example: Carbon

Electrons
• Orbit around the nucleus• Have negative (-) charge• Electrons = the number of protons

Electrons – Energy Levels
• Energy levels are in the electron cloud and around the nucleus
• Each level has a set number of electrons that the level can hold up to
• Outer most level is for chemical bonding• Energy levels are
accurate until the 5th energy level

Atoms have neutral charge• # of Protons (+) = # of Electrons (-) = 0 charge
• Example: Hydrogen
• How many electrons does C have?

Electrons orbit in “shells”• 1st shell can fit 2 electrons
• 2nd shell can fit 8 electrons2nd period/row
3rd period/row
1st period/row
• 3rd shells can fit up to 18 electrons

Reading and Using the Periodic Table
Mass

Atomic Number
• Definition: the number of protons in the nucleus
• Protons = Atomic Number = Electrons• Tells us the identity of the element.
Every element is defined by the number of protons in its nucleus

Atomic Mass
• Definition: the ~ mass of one atom of an element
• Tells us how much one atom weighs in atomic mass units.
