Miscellaneous
100
A type of mixture in which two or more substances are uniformly spread out. Milk is an example.
What is a homogeneous mixture?
100
An element category. These are shiny and conduct heat and electricity well.
What is a metal?
100
This subatomic particle has a positive charge.
What is a proton?
100
A pure substance that cannot be separated into a simpler substance. Composed of only one type of atom.
What is an element?
100
The force that acts on the surface of a liquid.
What is surface tension?
200
A combination of two or more substances that are not chemically combined.
What is a mixture?
200
An element that conducts heat and electricity poorly.
What is a nonmetal?
200
The smallest unit of an element.
What is an atom?
200
This substance is dissolved into something else.
What is a solute?
200
The type of model drawn to represent the atom of an element.
What is a Bohr model?
300
The atomic mass of an element can be found by adding these two subatomic particles.
What are protons & neutrons?
300
Appears to be a single substance. Composed of particles of two or more substances that are distributed evenly among each other.
What is solution?
300
Small particles that make up protons and neutrons, though scientists do not consider them to be the basic building blocks of matter.
What are quarks?
300
True or false: all solutions are liquids.
False.
300
Which electrons have more energy? Those closest to the nucleus or those furthest away from the nucleus?
The electrons furthest away.
400
In this type of mixture, particles are dispersed throughout, but particles are large enough that they settle out.
What is a suspension?
400
A solid changes directly into a gas, skipping the liquid state.
What is sublimation?
400
The atomic number is equal to these subatomic particles and identifies the element.
What are protons?
400
This is the substance into which something is dissolved.
What is a solvent?
400
Melting is this type of change because energy is gained by the substance as it changes state. (answer is not physical change.)
What is endothermic?
500
Pizza & fruit salad are two examples of this type of mixture in which different materials can be easily distinguished.
What is heterogeneous?
500
The resistance of a liquid or gas to flow.
What is viscosity?
500
A particle of a compound.
What is a molecule?
500
A pure substance composed of two or more elements that are chemically combined.
What is a compound?
500
What is involved in the change of the state of matter, also known as temperature.
What is energy?
