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
the smallest unit of an element that maintains the properties of that element.
atom
is related to the structure of the atoms in terms of number of protons and electrons in a neutrally charged atom.
atomic number
a substance made up of atoms of two or more different elements joined by chemical bonds.
compound
Which measurement label would be used for describing density of a liquid?
g/mL
a measure of the amount of matter in an object.
Mass
a substance that cannot be separated or broken down into simpler substances by chemical means.
element
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 group of atoms that are held together by chemical bonds
molecule
________________________: anything that has mass and takes up space
matter
What is the equation for volume of a regularly shaped cube or prism?
V=LxWxH
Term for finding the volume of an irregularly shaped object.
displacement
The particles that make up an atom
protons, neutrons, electrons
a solid whose atoms 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
Charges for each subatomic particle.
Protons positive
Electrons negative
Neutrons no charge
tells how much of one thing there is compared to another.
EX: each molecule of water has 2 hydrogen atoms for every 1 oxygen atom
ratio
__________________________: describes a substance's ability to change into a new substance with different properties.
chemical properties
The ratio of the mass of a substance to its volume.
density
a sample of matter, either a single element or a single molecule or compound, that has definite chemical and physical properties.
pure substance
relates to the complete amount of matter in the atom, the combination of protons and neutrons that make up that single atom.
atomic mass
the attractive force that holds atoms or subunits of atoms together.
chemical bond
