300
Define a molecule
A molecule is a substance that is made of two or more atoms. (H2) (H2O)
300
What is a control variable
What is a variable that stays the same to keep an experiment fair
400
These two parts of the atom make up the nucleus
What are protons and neutrons
400
If an atom has three protons and 4 neutrons, what is its atomic mass/weight?
What is 7 AMU (Lithium)
400
Define a compound
What is a type of molecule that is made of two or more different elements.
400
Define a dependent variable
What is the variable that a scientist is measuring. (time, distance, mass, speed, etc).
500
Describe where protons, neutrons, and electrons are located in an atom.
What is protons and neutrons make up the nucleus. Electrons move around the outside of the nucleus.
500
Explain why only the mass of protons and neutrons are taken into account to figure out an elements atomic mass/weight?
What is electrons are so small their mass does not change the overall mass of the atom
500
Describe why not all molecules are compounds
If a molecule is made from the same type of element it is not considered a compound
500
Define an independent variable
What is the variable that the scientist chooses to change throughout the experiment
