made up of
when there is not enough neutrons
protons and neutrons make up the nucleus
electrons are in the electron shells
necessary for an experiment
dependent variable changes based off of the independant variable
melting

types of changes in science
common physical changes that occur
a bar graph is similar to a line graph, bar graph uses a rectangular box and a line graph uses lines
kinetic theory explains the gas laws
v, t, & p is all used with gas law equations
when using the metric system, you have to convert inches, meters, and grams
a valence electron is the number of electrons in the last electron shells
