This step in the scientific method means to make an educated guess about what results you will find at the conclusion of your experiment
What is a hypothesis?
100
This is a pure substance that is only composed of one type of atom?
What is an element?
100
The protons and neutrons are located in the ____________ of the atom.
What is the nucleus?
100
These are the rows that go across the periodic table.
What is a period?
100
These are the columns (Top to bottom) in the periodic table.
What is a group or family (will accept either).
200
This means to review the results of your experiment and try to find patterns that will help you draw a strong conclusion.
What is to analyze your data?
200
This is two or more elements that have been chemically bonded.
What is a compound?
200
These are positively charged subatomic particles located in the nucleus of an atom.
What is the proton?
200
You can find the number of these two subatomic particles in any element by looking at its atomic number?
What are protons and electrons?
200
Families are grouped by the number of these which they hold in their outer shell.
What are valence electrons?
300
This is the step in the scientific method where you actually test your hypothesis.
What is the procedure or experiment?
300
This is two or more compounds or elements that have been combined but not chemically bonded and can ultimately be separated.
What is a mixture?
300
These are negatively charged subatomic particles located in the cloud.
What are the electrons?
300
You can find the number neutrons by doing this.
What is subtracting the atomic number from the atomic mass or weight?
300
Helium, Neon and Argon are all a part of this family.
What are the noble gases?
400
This is the variable that you observe changes in. If sunlight makes plants grow, plant growth would be this type of variable.
What is the dependent variable?
400
This type of mixture is mixed evenly. You would not be able to observe the different parts making up this mixture. An example would be salt water.
What is a homogeneous mixture?
400
These are neither positive or negatively charged subatomic particles. They are located in the nucleus?
What are the neutrons?
400
The number of protons, neutrons, and electrons in an atom of Ca.
What is 20, 20, and 20
400
Aluminum is this type of element.
What is a metal?
500
This is the variable that you change. If Michael Phelps shaves his chest to see if it makes him swim faster, hair removal would be this variable.
What is the independent variable?
500
This type of mixture is visibly made of different parts. An example would be concrete or chicken soup.
What is a heterogeneous mixture?
500
This is the cloud around the nucleus of the atom that is negatively charged.
What is the electron cloud?
500
The number of protons, neutrons, and electrons in an atom of P.
What is 15 protons, 15 electrons, and 16 neutrons.
500
Titanium is this type of element.
What is a non-metal
