How the elements are arranged on the periodic table.
What is Atomic Number (By number of protons)
100
Where is all the energy stored in an atom?
What is an electron in the shell, energy level, orbital?
100
When a reaction loses HEAT it called...
What is an exothermic reaction
100
An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced outside force.
What is inertia?
200
Amount of space something takes up.
What is volume?
200
Where do you look to find how many electrons an element has?
What is atomic number (equal to # of protons)
200
The rule that states atoms want to fill their outer shell for stability (usually 8 electrons)
What is the OCTET RULE?
200
What pH stands for and measures.
What is potential hydrogen. (Measures how many hydrogen ions a substance has).
200
What is the equation for Newton's Second Law? And explain it.
What is F = MA
Force = Mass x acceleration.
Force is greater when mass is greater.
The heavier the object, the more force it takes to get it to move (accelerate).
300
Measures how tightly atoms are packed together.
What is density?
300
Tells you how many VALENCE electrons and atom has.
What is GROUP/FAMILY number?
300
When atoms TRANSFER electrons and then become charged they form this type of bond.
What is an IONIC BOND?
300
When a substance has a pH between 0-7 it's called this. What is the strongest number for this substance? Give an example.
What is an ACID.
0 is the strongest - battery acid or stomach acid would be around a 1.
300
Force that pulls objects towards earth and the greater the mass, the greater the force pulling down.
What is Gravity (Gravitational pull)
400
Pure substance made up of only 1 kind of atom.
What is an element?
400
Tells you how many shells an atom has.
What is PERIOD NUMBER?
400
Elements on the periodic table that have 7 electrons in their outer shell and will make a salt with group 1.
What is a HALOGEN?
400
A Substance that speeds up a chemical reaction.
What is a catalyst?
400
A push or a pull
What is FORCE?
500
What are the properties of matter? (HINT:explain acronym)
What is SCHOoL?
S = Shape
C = Color
H = Hardness (Malleable and Ductile)
Oo = Odor!
L = Luster (Shine)
500
How to find number of neutrons?
What is subtract Atomic Number from Atomic Mass.
500
When oxygen and hydrogen get together they make this type of bond by doing what? WHY do they do this?
What is a covalent bond? To SHARE electrons and have full outer shells. To be STABLE.
500
What are the 2 parts that make up a solution? Explain each part and then give an example of a solution.
What is a solute (dissolved particle) and a solvent (does the dissolving).
Salt in water
Chocolate milk
Ice tea
Sugar in coffee...
500
Designs that resist drag and friction in the air are called what?
