All about matter.
States of Matter
The states of matter are gas, solid, liquid, plasma, and colliods. The atoms in gas move very fast. They move fast because the gas fills all of the space it can and takes the shape of the container or room. Liquid's atoms move fast but not as fast as gases atom's. That is because liquids can only take a certain amount of space up it can't grow or expand like gas can. A solid's atoms move very slowly. That is because it can't change it's shape or form.
The Parts of an Atom
The parts of atom's are electrons, neutrons, and protons. In an atom the protons and neutrons go in the nucleus and electrons go outside the nucleus. For the atom to have a positive charge it has to have more protons than electrons. For the atom to have a negative charge it must have more electrons than protons. For the atom to be neutral it will have the same number of protons and electrons. All atoms have two protons and neutrons. Only matter is made up of atoms.
