Ions Ion – Charged Atom Cation - positive charged atom Anion negative charged atom Charge equals the A group number
Poly atomic Ion - Charged particle formed by a group of covalently bonded atoms.
Formulas Molecular Formula – exact number and type of atoms present Empirical Formula – Simplest whole number ratio of atoms present in a molecule or compound.
Valence Electrons The number of electrons in the outer level of an atom. Equals the A group number
Ionic Bond bond formed by the giving or taking of electrons
Properties of Ionic Compounds Formed from a metal and a non metal Most are soluble in water Form crystalline lattices
Covalent Bond bond formed by the Sharing of electrons
Properties of Covalent Compounds Formed by two nonmetals Solubility varies The strongest bond
Polarity Slight charge differences in a molecule due to atoms having different electronegativity
Electronegativity The attraction an atom has for a pair of shared electrons
Polar Covalent Bond Bond formed with unequal sharing of electrons
Bond lengths The distance between the nuclei of two covalently bonded atom.
Ionic and Covalent Bonding 1. Bonding Atoms with unfilled valence shells are considered unstable. Atoms will try to fill their outer shells by bonding.
The Chemistry Of Dirt. What is Dirt Made OF? So, How do atoms Hook Together to make compounds and minerals and stuff like dirt? …… Well, I’m Glad you.
bond formed by the giving or Ionic Bond bond formed by the giving or taking of electrons.
Physical Science 1000 Bonding. Counting Electrons Total Electrons and Valence Electrons Valence Electrons – number of electrons in the outer shell of.
COVALENT BONDS Chapter 5 Section 3.
Ch 8 Review.
Chapter 4, Section 2 Covalent Bonds
Covalent Bonds. Form when two or more non-metal atoms SHARE electrons. There is no transfer of electrons.
Ionic Compounds Ionic Compounds (SALTS) formed by transferring electrons (giving/taking) occurs between a metal and a non-metal have an electro negativity.
Section 3 ~ Covalent Bonds
Ionic Bonding & Covalent Bonding. Ionic Bonding Ionic Bonding – TRANSFER of electrons Metals + Nonmetals = Ionic Bond.
