state of matter that has no definite shape or volume
Back
nonmetal
Front
element that lacks most of the properties of a metal, is not shiny, does not conduct electricity or heat well, is not malleable so it is called brittle or breakable.
Back
physical change
Front
change that does not produce new substances - melting an ice cube or ripping paper. You can get the ice back and the paper is still paper.
Back
ductile
Front
able to be drawn into thin wires
Back
liquid
Front
state of matter with a definite volume but no definite shape
Back
reactant
Front
substance that is changed in a chemical reaction
Back
properties
Front
characteristics used to describe an object
Back
evaporation
Front
change from a liquid to a gas at the surface of the liquid
Back
neutron
Front
particle that has no charge - located in the nucleus of an atom. You can figure out the number of neutrons by SUBTRACTING the atomic Mass minus the atomic number.
Back
state of matter
Front
any of the four physical forms of matter
Back
luster
Front
the way a material reflects light
Back
atomic mass
Front
total mass of the protons and neutrons in an atom
Back
atomic number
Front
number of protons in the nucleus of an atom. This is the same number as the number of electrons
Back
condensation
Front
change from a gas to a liquid
Back
chemical change:
Front
change that produces new substances - burning wood to make ashes or mixing mentos and coke. You can't get the wood or the mentos back.
Back
energy level
Front
place in an electron cloud where an electron is most likely to be found - rings. Remember, 2-8-18-32.
Back
electron
Front
particle that has a negative charge - located in rings outside the nucleus of an atom. You can figure out the number of electrons by looking at the atomic number of an element.
Back
solid
Front
state of matter with a definite shape and volume
Back
chemical bond
Front
force of attraction that holds atoms together
Back
atom
Front
smallest part of an element that can be identified as that element
Back
proton
Front
particle that has a positive charge - located in the nucleus of an atom. You can figure out the number of protons by looking at the atomic number of an element.
Back
chemical formula
Front
way of writing the name of a compound using chemical symbols
Back
nucleus
Front
center, or core, of an atom (where the protons and neutrons are located)
Back
element
Front
substance that CANNOT be chemically broken down into simpler substances
Back
chemical reaction
Front
process in which new substances with new chemical and physical properties are formed
Back
matter
Front
anything that has mass and takes up space
Back
chemical equation
Front
statement in which chemical formulas are used to describe a chemical reaction
Back
malleable
Front
able to be hammered into different shapes
Back
sublimation
Front
change from a solid directly to a gas
Back
molecule
Front
smallest part of a substance that has all the properties of that substance - more than one element, like hydrogen and oxygen make water
Back
metal
Front
element that has the property of shiny luster, ductility, and malleability
