Measurement
Fill in the blanks:
Matter is anything that has BLANK and BLANK.
MASS and VOLUME
What state of matter describes the following statement?
Particles arranged in a fixed pattern and have a definite shape and volume.
Solid
What is the smallest unit of an element?
An atom
What are the smallest units of matter?
Electrons
What is it called when substances are combined but can be easily separated and are not evenly distributed?
A mixture
Fill in the blank:
Mass is the amount of BLANK in something
MATTER
What state of matter describes the following statement?
Particles fill out the bottom of a container and have a definite volume but can change shape.
Liquid
What is a substance that cannot be broken down?
An element
What is the center of the atom called?
Nucleus
In a solution, what is the part that dissolves?
The solute
(usually a powder)
Fill in the blank:
Volume is the amount of BLANK matter occupies.
SPACE
What state of matter describes the following statement?
Particles vibrate in place.
Solids
What is used to organize the elements?
The Periodic Table of Elements
What are the two types of particles in the center of an atom?
Neutrons and Protons
The solvent is usually what state of matter?
A liquid
What is the formula for finding the volume of a rectangle?
L x W x H
Length x Width x Height
(any order is fine)
What state of matter describes the following statement?
Particles have no pattern and spread to fill a container.
Gas
What are substances made of two or more elements?
Compounds
(or molecules)
What is the big difference between the Bohr Model and the Modern Model of Atoms?
They way they show electrons!
(Bohr models show electrons moving in fixed circular patterns, but the Modern Model shows that electrons move about in much more complex patterns.)
What is it called when a solution can no longer dissolve any more solute?
Its saturation point
What term describes how tightly packed an items molecules are?
Density
What state of matter describes the following statement?
Has a definite volume but changes shape and particles slip and slide.
Liquid
How are elements combined in substances?
Chemically
Electrons = negatively charged
Protons = positively charged
They are balanced because the electrons are electrically charged and the protons are positively charged and this balances out the atom.
How do you describe the strength of a solution?
Diluted and Concentrated
(Dilution and Concentration)
