The ability to do work.
What is energy?
200
He created the Periodic table.
Who is Mendeleev?
200
An electrostatic attraction forms between atoms when they share or transfer valence electrons.
What is a chemical bond?
200
A molecule made of two atoms (whether of the same element or not).
What is a chemical reaction?
200
This is the push or pull on an object.
What is force?
400
Daily Double
What is kinetic energy?
400
There are 118 of them.
How many elements have been discovered?
400
This principle states that atoms generally are most stable when they have eight electrons in their valence energy level.
What is the octet rule?
400
A combination of chemical formulas and symbols that models a chemical reaction.
What is a chemical equation?
400
The branch of physics that studies forces and how they can change an object’s motion.
What is dynamics?
600
Stored energy that can be used later.
What is potential energy?
600
The scientists who study elements and other materials.
What are alchemists?
600
A chemical bond formed as a result of two atoms sharing valence electrons.
What is a covalent bond?
600
SI fundamental unit for the quantity of matter in a substance; a count equal to 6.022 × 1023.
What is a mole?
600
What is contact force?
800
This can be used to heat water.
What is solar energy?
800
These elements are located on the far right side of the periodic table.
What are nonmetals?
800
This type of molecule is made of two atoms (whether of the same element or not).
What is a diatomic molecule?
800
Daily Double
What is an example of a chemical change?
800
The tendency of matter to resist changes in its motion.
What is inertia?
1000
The sum of any kinetic energy and all the forms of potential energy in a system.
What is mechanical energy?
1000
An electron found in the outermost energy level of a neutral atom.
What is a valence electron?
1000
Bonds that form between a metal and a nonmetal.
What is an ionic bond?
1000
This is the mass of one mole of a substance.
What is molar mass?
1000
A force that acts between objects that are not touching; also called force at a distance.
What is a field force?
