Chemistry
atom - ANS - smallest part of an element that can be identified as that element
\atomic mass - ANS - total mass of the protons and neutrons in an atom
\atomic number - ANS - number of protons in the nucleus of an atom. This is the
same number as the number of electrons
\chemical bond - ANS - force of attraction that holds atoms together
\chemical change: - ANS - 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.
\chemical equation - ANS - statement in which chemical formulas are used to
describe a chemical reaction
\chemical formula - ANS - way of writing the name of a compound using chemical
symbols
\chemical reaction - ANS - process in which new substances with new chemical
and physical properties are formed
\coefficient - ANS - number that shows how many molecules of a substance are
involved in a chemical reaction
\condensation - ANS - change from a gas to a liquid
\ductile - ANS - able to be drawn into thin wires
\electron - ANS - 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.
\element - ANS - substance that CANNOT be chemically broken down into simpler
substances
\energy level - ANS - place in an electron cloud where an electron is most likely to
be found - rings. Remember, 2-8-18-32.
\evaporation - ANS - change from a liquid to a gas at the surface of the liquid
\freezing - ANS - change from a liquid to a solid
\gas - ANS - state of matter that has no definite shape or volume
\halogens - ANS - elements that make up Group 17 in the periodic table
\liquid - ANS - state of matter with a definite volume but no definite shape
\luster - ANS - the way a material reflects light
\malleable - ANS - able to be hammered into different shapes
\matter - ANS - anything that has mass and takes up space
\melting - ANS - change from a solid to a liquid
\metal - ANS - element that has the property of shiny luster, ductility, and
malleability
