What is Density?
The amount of particles in a given space, giving the object more mass
-
What is special about the density of 1.00
It is the density of water, therefor objects below that density float, and objects above that density sink
-
What is the formula for calculating density?
Denisty = Mass over Volume
-
How do you test for oxygen gas?
You dip a glowing splint into a test tube, and you should see bubbles rise adn fall/exploding, and the flaming splint should ignite and then smolder out.
-
|How do you test for gas?
Insert a flaming splint into test tube. You should see bubbles producing gas.smoke, loud pop sound, and the splint burns out .
-
How do you test for carbon Dioxide gas?
Pour a small amount of liemwater into a test tube. Fill the remainder with Carbon dioxide, and then plug with a stopper. When shaken, there should be a foggy white cloud inside the tube.

What is the order of electrons based on the Bohr-Rugerford digram?
-
Name and order the five scientist the discoverd and built apon atomic theory
- Dalton
- Thompson
- Rutherford
- Bohr
- Chadwick
-
What are Daltons discoveries and his flaw?
- Atoms are the smallest unit of matter in the shape of Spheres
- All atoms are the same in a given element
- FLAW: Does not explain why electrons have electric charge
-
What are Thompson's Experiment, discoveries and his flaw?
- Experiment; Cathrode Ray tube Experiment
- Discoverd that atoms have positive and negitive charges
- FLAW:Does not explain why the atom's would not implode, as opposite charges attract.
-
What are Rutherford's experiment, discoveries and his flaw?
- Experiment: Gold foil experiment
- Discoverd that positive charges are located in the nucleas of the atom, and negitive charges on the outside
- FLAW:Does nopt explain why the negitive charges did not attarct to the positive charges.
-
What are Daltons discoveries and his flaw?
- Discoverd that electrons have energy levels
- FLAW; Cannot identify where the electrons are
-
What are Chadwick's discoveries and his flaw?
- Found isotopes in various elements
- Idenifield that mass changes with the amount of neutron's present
-
How do you find the number of protons?
The number of prontons equal the atomic number
-
How do you find the number of electrons?
The number of electrons equal the amount of protons
-
How do you find the atomic mass?
The sum of the protons and neutrons
-
How do you find the number of neutrons?
By subtracting the atomic number from the atomic mass
-
