Protons, Neutrons, and Electrons

18swennoa — 2015-09-14 19:31:06 UTC

Protons and Neutrons have about the same mass.

Protons have a positive charge, Neutrons have no charge, and Electrons have a negative charge .

Together they make a nucleus.

Electrons circle around the nucleus.

Atomic Number/Mass Number

18swennoa — 2015-09-14 19:49:51 UTC

The atomic number is the number of protons in the nucleus.

The mass number is the total amount of protons and neutrons in the nucleus.

Isotopes

18swennoa — 2015-09-14 19:56:09 UTC

Isotopes have a larger amount of neutrons.

Chemical Compounds/Chemical Bonds

18swennoa — 2015-09-14 20:01:57 UTC

A chemical compound is a substance formed by the chemical combination of two or ore elements in definite proportions.

There are two types of chemical bonds they are ionic bonds and covalent bonds.

Ionic bonds are formed when 1 or more electrons are transferred from one atom to another.

Covalent bonds are when they share instead of transferring.

Van der Walls Forces

18swennoa — 2015-09-14 20:09:24 UTC

When molecules are close together a slight attraction can develop between oppositly charged regions of nearby molecules.

Hydrogen Bonding

18swennoa — 2015-09-17 21:32:51 UTC

The attraction between a hydrogen atom with a partial positive charge and and another atom with a partial negative charge.

Cohesion/Adhesion

18swennoa — 2015-09-17 21:40:59 UTC

Cohesion is the attraction of molecules of the same substance.

Adhesion is the attraction of molecules of different substances.

Heat Capacity

18swennoa — 2015-09-17 21:43:01 UTC

Multiple hydrogen bonds between water molecules is that it takes a large amount of heat energy to cause those molecules to move faster.

Acids and Bases (Ph Scale)

18swennoa — 2015-09-17 21:51:28 UTC

Acid is any compound that forms a H+ ions in a solution.

Base a compound that produces OH- ions in solutions.

Ph Scale measurement system of the H+ ions in solutions.
