What is proton (+), electron (-) and neutron (none)
100
The four states of matter
What is solid, liquid, gas and plasma
100
An example of a physical and chemical property of paper.
What is physical property = white, thin, and chemical property= ability to burn.
100
The stable gas that is happy with 2 in the outer shell
What is helium
200
The amount of space something takes up.
What is volume
200
What is the difference between a suspension and a solution
What is suspension is when a mixture is heterogenous, then when shaken becomes homogeneous and after time settles out to be heterogenous again, whereas a solution is just a mixture that is homogenous at all times.
200
How the particles in each state move and what their volume is.
What is solid = vibrate and definite, liquid= freely and no definite, gas = fast and no definite
200
Explanations and examples of size independent and dependent physical properties
What is independent = doesn't matter the size of the object- density because it is a ratio, boiling point, freezing point, and dependent = it does matter the size - mass, volume
200
The differences between groups and periods
What are groups are vertical and show the number of electrons in the outer shell. Periods are horizontal and indicate number of shells.
300
10 km = ________ m
What is 10,000 mters
300
Three ways compounds are different from mixtures
What is compounds are bonded, mixtures are blended. Compounds have formulas and exact recipes and mixture don't. Compounds you can't tell what it is made of because the elements properties change when bonded and mixture you can because the ingredients keep their original properties.
300
When a solid changes directly to a gas
What is sublimation
300
The density of water and the density of an object with a mass of 50 grams and a volume of 100 cm3
What is 1g/cm3 for waters and 0.5g/cm3 for the object
300
These are the two people that first organized the periodic table and how they organized it.
What is Mendeleev - by atomic mass and Mosely by atomic number
400
Metric base unit for finding the weight of an object.
What is the gram.
400
What are names and examples of the 2 different types of mixtures.
What is homogenous ( vanilla wafer cookie) and heterogenous ( chocolate chip cookie)
400
Surface tension
What is when a needle floats on water due to the uneven forces acting on the surface of the water, pulling the atoms closer together and making a "Thicker Film" on top.
400
Daily Double
What are the 7 steps of the Scientific method?
400
The group that is more active as you go down and highly reactive with water
What is the alkaline metals.
500
The prefixes for the metric system
What is Kilo(k), Hecto ( h) , Deca (da), unit ( m,l,g),Deci (d),Centi (c) Milli (m) or Karter Has Died Man Don't Care Much
500
The number of atoms and elements on the formula H2 He4 O6.
What is 12 atoms total and 3 elements, Hydrogen has 2,Helium has 4 and Oxygen has 6.
500
A description and name of the two different types of solids.
What is crystalline with a 3-D pattern of particles like salt and amorphous with random arrangement of particles like in rubber
500
Definition of the Law of Conservation of Mass and an example with a physical and chemical change.
What is the "mass doesn't change if a physical or chemical change occurs". For example, in a physical change the mass of the candle stayed at 0.7 grams before and after it was melted. When the candle burnt (chemical change) the mass went from 0.7g to zero- but the mass wasn't lost it went into the air as a gas.
