Matter is made up of
Atoms (particles)
Mass is..
The amount of matter in an object. The more particles you have the heavier the mass is. The less particles you have the lighter the mass is.

I am found in Group 15 Period 5. Who am I?
Antimony
I have the least amount of kinetic energy
Solid
I have a metal square that is 2 cm on each side. It's mass is 64g. what is the density of the metal rectangle? (Hint: Do LxWxH to find the volume)
D=M/V which means 2x2x2= 8
Volume=8
Mass=64
64/8=8. 8 is the density of the metal rectangle
What is conductivity?
Metals that are generally electrically conductive.
Can nonmetals be easily broken
Yes, they are brittle
On the periodic table I am located in between metals and nonmetals. At times people call me?
Stair-Steppers
I do not have a definite volume
Gas
