QuarksQuarks are the basic building blocks of matterThere are three types of families of quarksThe first family consists of ups and down quarks which forms protons and neutronsThe second family consists of strange and charm quarks which are used in high energiesThe third family consists of top and bottom quarks which are only used in very high energies

Atomic StructureAccording to the bohr atomic theory, a basic unit of an element is an atomProtons, neutrons, and electrons circulate around the nucleusAtomic mass= Number of protons and number of neutrons Mass of proportion= Mass of neutron

IsotopesIsotopes are atoms with a neutron number different from the majorityIsotopes will have a different atomic mass from the majority of atoms of that elementThe nuclei are less stable than normalThe nuclei rapidly change to a more stable form and release energy

Ionic BondsAn ionic bond is formed when one atom gives or accepts one or more of its valence electrons to another atomUnder here is a Sodium Ionic bond

Covalent BondsA covalent bond is formed when two non-metal atoms share valence electronsWhen electrons are shared between to metallic bonds than a metallic bond is formedCovalent bonds involve complete sharing at electrons and occurs mostly between atoms that have partially filled outer shells.If the atoms are similar in negativity, than the electrons will be sharedBurning MoleculesBy raising the temperture of a molecule, we speed up how fast it movesThe faster it moves the stronger the reactionAn example of the everyday burning molecules is nitrogen and oxygenEach bond has two electronsWhen a smash happens, an atom gets one electron

How does Biology relate to Matter and Energy?With Animals and plants, we all have cells that make up who we are. Inside a cell we have Protrons, neutrons, and electrons. These are like steps. First comes Matter and Energy, then comes cell, then DNA, and etc.
