Atoms and Matter
1Elements are...
- Magnesium
- Gas
- made up of one type of atom
- Solid
2Neutron
- In nucleus
- Most important partical
- Positive charge
- Neutral charge(0) in nucleus; mass is 1.6750 x 10^-27
3Matter
- Love
- Chemistry
- Tree
- Physical substance in general
4Atomic Number
- Equal to neutrons
- Equal to mass
- Equal to protons
- Equal to Electrons
5Periodic Table
- List of Elements
- Iron
- Oil
- Valence Electrons
6Proton
- Equal to nuetron
- Positive charge(+1) in nucleus; mass is 1.6726 × 10-27 kg
- Doesn't change elements
- Equals mass
7Cation
- Negative Ion
- Positive Ion
- Atom must gain one or more electrons
- Atom must lose one or more electrons
8Atom
- No charge
- Smallest unit known
- Purple
- Makes up life
9Physical Properties
- Ice in water
- Car crashing
- Punching a wall
- Measured without changing the composition of matter
10Electron
- Doesn't affect elements
- More electron can change an element
- Proton
- Negative charge(-1) in orbits; mass is 9.109 × 10^-31 kg
11Mass Number of Elements
- Neutron+Electron
- 5.2
- Proton+Neutron
- Electron
12Gas
- Element
- Air
- Vapor or Steam; Molecules move freely
- Group 18 on periodic table
13Valence Electrons
- Any electron on furthest orbit
- Atom
- Protons+Electron
- 5
14Isotopes
- Gain protons
- Same number of protons but different number of neutrons
- Electron change isotopes
- Gain electrons
15Ions
- Positive Charge
- Atoms
- Neutral charge(0) in nucleus; mass is 1.6750 x 10^-27
- Negative Charge
16Net Charge
- Mass
- +1
- -1
- Protons-Electrons
17Liquid
- Molecules Connected
- Molecules still attracted to each other but aren't connected
- water
- Tree
18Solid
- Ice; Molecules connected
- Molecules Near but not connected
- Rock
- Molecules seperate
19Chemical Properties
- Acid
- Properties evident during, or after, a chemical reaction
- Size
- Color
20Anion
- Atom must gain one or more electrons
- Atom must lose one or more electrons
- Positive Ion
- Negative Ion
21Density Equation
- V=Distance/Time
- F=MassxAcceleration
- D=Mass(g)/Volume(mL or cm^3)
- P=VoltagexCurrent
