What is a mixture?
200
The value obtained by adding protons and neutrons.
What is mass number/atomic mass?
200
When atoms share electrons to obtain a noble gas configuration.
What is a covalent bond?
200
When a molecule has a slightly negative and positive charge in different areas.
What is polarity?
200
The equation you would use to calculate the density of water.
What is D=m/V
300
A type of mixture where everything is unevenly distributed.
What is a heterogenous mixture?
300
A group of elements that has 8 valence electrons
What is a noble gas?

When a metal bonds with a non-metal.
What is an ionic bond?
300
The capillary action (as a result of hydrogen bonding) that allows plants to move nutrients from the roots UP to the rest of the plant.
What is adhesion?
300
The nickname given to water for its extremely important role in biological molecular reactions.
What is the "Universal Solvent"

What is a compound?
400
This element contains 8 protons.
What is Oxygen
400
The type of bond formed between an element from group 5 with group 6.
What is a covalent bond?
400
The phenomenon caused by cohesion (as a result of hydrogen bonding) that allows certain insects to walk on water.
What is surface tension?
