1. electrons elements with properties intermediate between those of metals and nonmetals
2. metals
elements that are malleable, polish to a luster, conduct heat and electricity well and tend to lose electrons in a chemical reaction
3. period
a vertical column on the periodic table
4. compound
two or more elements that have chemically combined
5. solution
positively charged, subatomic particles found in the nucleus of the atom
6. protons
negatively charged, subatomic particles
7. group
a homogeneous mixture whose particles are too small to reflect or scatter light
8. metalloids
a horizontal row on the periodic table

Gas is a type of carbon, i think lol

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
