1. Intro to Atoms

Look around you. Everything is made of something. Paper is made from trees, your shirt is made of cotton, and a soda can is made from aluminum. But if you look deeper, everything is made of matter. "Matter is everything that has mass and takes up space (Frank,Little, Miller, 6)." But matter is made up of something too. Matter is made up of elements, which is a pure substance,and elements are made up of atoms
Atoms are made up of protons, which are positivity charged, neutrons, which are neutral or have no charge, and electrons, which are negativity charged. There are two sections of an atoms; the nucleus and the cloud of electrons. Protons and neutrons are in the nucleus, and electrons are outside the nueclus. An atoms contains an equal number of protons and electrons, and they also contain a number of neutrons.

2. Valence Electrons and Bonding

An atom has valence electrons, elcetrons that have the highest amount of energy and the elcetrons that are held most loosely. "The number of valence electrons in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other bonds (Frank, Little, Miller, 12)." To show valence electrons, you can use a electron dot diagram, which includes the symbol of the element surrounded by dots representing valence electrons
Atoms usually react in a way so other atoms become more stable. To do this one of two things can happen; Either the number of valence electrons increass to eight (a full valence shell),or the atom gives up valence electrons. When this happens, atoms become chemically bonded. A chemical bond is the force of attraction that hold two atoms together as a result of arragements by the atoms.

3. The Periodic Table

The periodic table is a chart where you can find all the elements . The elements are arranged according to their atomic number, which is "the number of protons in the nucleus of an atom (Quizlet)"also in the way in which their electrons are organized.(Challoner 12)."elements at the beginning of each horizontal row,or period, have one electron in three outer electron shell of their atoms."(Challoner 12)
There are different names for some of the groups. Group 1 is called the alkali family, and they have one valence electron. Group 2, or the alkali earth family, has 2 valence electrons. Group 17, the halogens, have 7 valence electrons. "The elements of the last group of the table,group 18,have full outer electron shells,and are inert,or unreactive. These elements are called the noble gases."(Challoner 12)".
