Bonds and Polarity

Bio Week 1

Ionic Bond

The attraction between cations and anions

Covalent Bond

When 2 atoms share an electron

Hydrogen Bond

Noncovalent attraction between a hydrogen and an electromagnetic atom (F,O,N)

Bonding Capacity

number of chemical bonds an atom can form (usually determined by # of unpaired valence e^-)

Electronegativity (what is the trend and which CHON have similar electronegativity)

a measure of how strongly an atom pulls electron towards themselves (CH and NO)

Polar

overall charge is unevenly distributed

Nonpolar

fair sharing in electrons

Hydrophobic

repel water (usually nonpolar and nonionic)

Hydrophillic

water - loving (polar)

Solvent

solution that acts as the dissolving agent

Solute

things that are being dissolved

Dissolution

process of. asubstance dissolving into another and spreads out evenly

Solubility

max. amount of a substance that can siddolve ina given amount of solvent @ a specific temp. and pressure
