Protons, Neutrons, Electrons:

17sennmac — 2014-09-08 17:03:07 UTC

Protons and Neutrons are found inside

of the Nucleus and Electrons are found

orbiting the nucleus.

Atomic Number/Mass Number:

17sennmac — 2014-09-08 17:10:15 UTC

Atomic number is the number of protons

in the nucleus of an atom. Mass number is the

total number of protons and

neutrons in a nucleus.

Isotopes:

17sennmac — 2014-09-08 17:12:43 UTC

Two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons

Chemical Bonds

17sennmac — 2014-09-08 17:14:54 UTC

An attraction between atoms that allows the

formation of chemical substances

that contain two or more atoms. Opposite

charges attract.

Van der Walls Forces

17sennmac — 2014-09-08 17:19:19 UTC

Van der Waals forces include attractions and repulsions between atoms, molecules, and surfaces.

Hydrogen Bonding:

17sennmac — 2014-09-08 17:21:57 UTC

The electromagnetic attractive interaction between

polar molecules, , in which hydrogen is bonded to a highly

electronegative atom, such as nitrogen, oxygen, or Fluorine.

Polarity:

17sennmac — 2014-09-08 18:09:03 UTC

Having two opposite electrical charges.

Cohesion/ Adhesion:

17sennmac — 2014-09-08 18:14:20 UTC

Cohesionis the property of like molecules (of the same substance) to stick to each other due to mutual attraction. Adhesion is the property of different molecules or surfaces to cling to each other.

Heat Capacity:

17sennmac — 2014-09-08 18:18:04 UTC

Heat capacity, or thermal capacity, is a measurable physical quantity; it's the ratio of the heat added to an object to the resulting temperature change

Solutions vs suspension:

17sennmac — 2014-09-08 18:20:50 UTC

A solution is a mixture in which other substances (solutes) are dissolved. Suspension is a mixture of liquids with particles of a solid which may not dissolve in the liquid.

Buffers:

17sennmac — 2014-09-08 18:24:11 UTC

A buffer is a solution that can resist pH change

upon the addition of an acidic or basic components.

Acids/ Bases (Ph)

17sennmac — 2014-09-08 18:26:38 UTC

The strength of an acid or base in a solution is measured

on a scale called a pH scale. The pH scale is a measure of the

hydrogen ion concentration. A base is a substance that is slippery

to the touch and tastes bitter. An acid is a chemical substance

whose solutions are characterized by a sour taste and have the

ability to turn blue litmus red.
