Chapter 2 Nature Of Matter Flashcards
Isotopes
A element that differs in the number of neutrons
Element
A pure substance containing of one type of atom
Ionic Bond
A bond formed when 1+ electrons are transferred
Covalent Bonding
Electrons (e-) are shared between atoms
Ex. H2O, C6H2O, CH4
Vander Waal Forces
Intra-Molecular attraction
Ex. Hydrogen Bonding
Hydrogen Bond
Attraction between a hydrogen atom on one H2O molecule and the oxygen of another H2O molecule
Polar
A molecule in which the charges (-/+) are not distributed evenly
Cohesion
Attraction between molecules of the same substance
Surface tension
Skin on H2O due to cohesion
Adhesion
Attraction between molecules of different substances
Mixtures
Material composed of 2 or more compounds that are PHYSICALLY mixed
2 Main Types: Solution/ Suspension
Solution
Ions disperse in water evenly
Solute
Substance that is dissolved
Solvent
Substance that does the dissolving
Water, ect.
Suspensions
Mixture of H2O and non dissolved material
Blood
