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

What makes Al-27 different than Al-33?

• atomic masses

• number of neutrons

• number of protons

• number of electrons

• mass number

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

Multiple Select

What do numbers 1, 2, 13, 14, 15, 16, 17, 18 at the top of the Periodic Table tell you?

• number of rings around the nucleus

• number of valence electrons

• number of protons

• group number

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

Multiple Choice

What chemical bond allows metals to be ductile?

• ionic bond

• metallic bond

• covalent bond

Multiple Choice

What would silicon and iodine do with their valence electrons when bonding?

• share them

• transfer them

• create a sea of electrons

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)

Find the binary ionic compound

• iron (II) oxide

• carbon dioxide

• lithium chloride

Binary Covalent Compound

• Bi- means 2

• 2 nonmetals

• Only the second element ends in -ide

• Use Greek Pre-fixes

• Don't use the prefix mono- on the first element

• Second element always has a pre-fix

Polyatomic Compounds

• Poly- means many (2 or more)​

​

• Use the Table of Polyatomic Ions on your Periodic Table of Ions

​

• Use parenthesis when you criss-cross a oxidation number (charge) that is 2 or greater to the polyatomic ion.

​

• Reduce oxidation numbers (charges) if you can
