Chapter 2 Flashcards
What are the structure of atoms
Proton, Neutrons, and Electrons
Neutrons weigh
1 amu
Electrons weigh
0amu
Protons and Neutrons are found in
The nucleus
What are the three types of mixtures
Solutions, Colloids and Suspensions
Colloids
Gives solution cloudy or milky look
Colloids and suspensions
Are heterogeneous mixtures
Colloids
Do not settle out
What is a mole
The sum of atomic weight measured in grams
1 mole of a compound is equal
To it’s molecular weight
Name the bonds
Ionic, Covalent, and Hydrogen bonds
This bond completes the transfer of electrons
Ionic bonds
Are atoms that have gained or lost and electrons and become charged
Ions
In ionic bonds protons and electrons
do NOT equal
This bond involves the transfer of valence shell of electrons from one atom to another
Ionic bond
Anions and Cations are found in
Ionic bonds
Anions have what charge
Negative
Atom that gained one or more electrons
Anion
Atom that lost one or more electron
Cation
Cations have what charge
Positive
Which bond is formed by sharing two or more valence shell electrons between two atoms
Covalent bonds
This bond results in electrically balanced
Non polar covalent bonds
Attractive force between electropositive hydrogen of one molecule and an electronegative atom of another molecule
Hydrogen bonds
Water is
Inorganic
