- 1Quantitate Informationinfo that
a. can be measured
b. usually includes numbers - 2Qualitative Informationinformation that is
a. descriptive
b. does not include numbers - 3Atomsbasic unit of matter
- 4Elementsconsist of only one type of atom
- 5Nucleusholds protons/neutrons
- 6Protonpositive
located in the nucleus - 7Neutronno charge, Neutral
- 8Electronnegatively charged, located outside the nucleus
- 9Energy Levels1st level - holds 2
2nd level - holds 8
3rd level - holds 8 - 10Valence ElectronsThe electrons in the outermost energy level
- 11Atomic Number- the identity of an element
- the number of protons equals the atomic number
- number of protons is also equal to the number of electrons
- 12Atomic Mass (AKA: Mass Number)number of protons plus the number of neutrons
- 13BondingGoal: to get the outer energy level filled
- 14Ionic BondA transfer of electrons
- 15Ionsatoms wit an excessive positive or negative charge
- 16Covalent BondSharing of electrons
- 17Hydrogen BondOccurs between two - NOT within them
Occurs between hydrogen and some other type of atom
Weaker then ionic and covalent bonds
- 18What happens when atoms bond?Molecules are formed
- 19Molecular FormulaLetters and Numbers (H2O, CO2)
- 20Structural Formulashows the arrangment of atoms
- 21What is the job of pH?tells you how acidic/basic a sollution
- 22What is a buffer?Chemical that minimizes the change in pH
- 23What is measured when you're measuring pH?The amount of hydrogen ions
- 24What happens when Hydrogen Ions increase when measuring pH?pH goes down
- 25What happens when number of hydrogen ions decreases when measuring pH?pH goes up
