Atoms

Atoms

Atoms make up molecules in the universe.Atom->(Greek translation) Something that cannot be split

Atoms consists of protons, neutrons and electrons. Protons-> Large with positive electric chargesNeutrons-> Large with no electrical chargeElectrons-> Small with negative electric charges

Electrons: Circle around the nucleus in random circles.

Nucleus: Consists of protons and neutrons

Atomic structure of silicon. 3 electron shells.Number of electrons in each shell (arranged from inner shell to outer shell). In this case, 1st shell-> 2 electrons2nd shell-> 8 electrons3rd shell-> 4 electrons

Return to Molecules

Atoms are neutral(number of protons are equal to electrons, positive charges cancel out negative charges).Atoms can be said to be stable.
