metals are on the left side and nonmetals are on the right side and there is metalloids are on the right side to but its called the stares

protons are is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron. If isolated, a single proton would have a mass of only 1.673 ? 10-27 kilogram, just slightly less than the mass of a neutron.

electrons is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels.

neutrons with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons, each with mass approximately one atomic mass unit, constitute the nucleus of an atom, and they are collectively referred to as nucleons. Their properties and interactions are described by nuclear physics.

Francium is the most reactive and the not reactive is Noble gases

If you know the correct patent number, you can find the patent application by searching for it on the U.S. Patent and Trademark Office's website.

mass number is neutrons and protons

atomic number is how many there are in the nucleus

subtract the atomic number and the mass number

Carbon has four valence electrons and here a valence of four. ... In chemistry, a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

the reactants are on the right side and the products are on the left

Chemical change is any change that results in the formation of new chemical substances but to a Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.

There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
