Atoms

• Atoms make up elements

• Atoms are identified by their atomic number

• Atoms are neutral because the number of positive protons equal the number of negative electrons.

• Atoms are made of sub-atomic particles called - protons, electrons, neutrons

• Atoms have 3 parts - Nucleus, Electron cloud, sub-atomic particles

Multiple Select

Click all the things that are positive in an atom.

• proton

• nucleus

• neutron

• electron cloud

Isotopes

• Different versions of the same element

• Everything is the same except......

• Different number of neutrons

• Different atomic masses

• Different mass numbers

Electron Configuration

Reminders

• Electron Configuration shows you the configuration of the

  electrons in the rings and orbitals (s,p,d,f)

• Noble Gas Configuration starts with the Noble Gas that is on the row above the element you are configuring.

Ions

​2 Types of Ions

CATIONS are positive because they give their electrons away - metals become cations

ANIONS are negative because they receive electrons - nonmetals become anions

Chemical Bonds

• Covalent Bond - nonmetals sharing valence electrons

• Ionic Bond - metal and nonmetals transferring electrons creating ions

• Metal Bond - cations and a sea of electrons

Multiple Select

Why do elements BOND?

• to follow the octet rule

• to look like a Noble Gas

• to become happy

• to become stable

Binary Ionic Nomenclature

• Bi- means 2

• between a metal and a non- metal or Cation and Anion

• Second element ends in -ide

• ​Reduce oxidation numbers when possible

• Criss-Cross or use the Drop and Swap Method with oxidation charges

  Use Roman Numerals, when naming, a metal with multiple oxidation numbers (charges)
