Explain why the following statements are true: 1) all matter is made up of atoms. 2) an electron with a proton equals a neutral charge. 3) all atoms are in constant motion. explain using complete sentences and will give brainliest to the best answer explain all of the ! thx

1.Atoms combine to form molecules which in turn are what makes up matter.

2.Electrons carry negative charges and protons carry positive charges. While protons have far more mass the number of protons and electrons in a stable atom is the same. These charges cancel each other out. If there is an imbalanced then the atom is radioactive and decays until it reaches stability.

3.According to the kinetic theory of matter, "All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases."
