Lesson 1
Which measurement label would be used for describing density of a solid?
g/cm3
__________________________: properties that include mass ,volume, density and state of matter.
physical properties
__________________________: a measure of the amount of matter in an object.
mass
____________________________________: is related to the structure of the atoms in terms of number of protons and electrons in a neutrally charged atom.
___________________________________: one, two, or three letters that represent each element.
element symbol
Which measurement labeling would be used for labeling surface area?
cm2
Which measurement label would be used for describing density of a liquid?
g/mL
__________________________: the ratio of the mass of a substance to the volume of the substance.
density
___________________________________: an arrangement of the elements in order of their atomic numbers such that elements with similar properties fall in the same column, or group
periodic table
___________________________________: a sample of matter, either a single element or a single compound, that has definite chemical and physical properties.
pure substance
________________________: anything that has mass and takes up space
matter
What is the equation for volume?
V=LxWxH
Why is an iceberg able to float?
The volume of the iceberg is greater than the volume of an equal mass of water.
_________________________: a substance that cannot be separated or broken down into simpler substances by chemical means.
element
__________________________________: a solid whose atoms, ions, or molecules are arranged in a regular, repeating pattern.
crystal
__________________________: the amount of space that an object takes up or occupies.
What is the equation for density?
D=M/V
__________________________: a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe.
weight
___________________________________: the smallest unit of an element that maintains the properties of that element.
atom
__________________________________: tells how much of one thing there is compared to another.
ratio
__________________________: describes a substance's ability to change into a new substance with different properties.
chemical properties
Which labeling would describe a straight line measurement?
cm
___________________________________: a substance made up of atoms of two or more different elements joined by chemical bonds.
compound
___________________________________: relates to the complete amount of matter in the atom, the combination of protons, neutrons, and electrons that make up that single atom.
atomic mass number
1.___________________________________: a group of atoms that are held together by chemical bonds; is the smallest unit of a compound that keeps all the properties of that substance.
2.__________________________________: the attractive force that holds atoms or subunits of atoms together.
