Atoms

1. Periodic table

   • The groups in the periodic table are the columns we find in there.
   • The periods are the lines or rows we find on the periodic table.
   • Metals
     • The metals are classified by their valence electrons. Most commonly they have from one to three valence electrons. They can't react with other metals but they can react with other elements. Furthermore, metals with 1 valence electrons are especially reactive.
     • Nonmetals
       • Nonmetals have a lot of properties. In difference to metals, nonmetals atoms do react with other nonmetals and metals. The levels of reactivity, are based on the number of valence electrons in the atoms of the elements. Other important about these atoms is that they commonly have less density than metals atoms.
     • Metalloids
       • Metalloids have properties from both metals and nonmetals. In addition, metalloids are hard, brittle, and reactive. Every metalloid is solid at room temperature. A metalloid is good at conducting electric currents. Metalloid conductivity depends on its temperature, light exposure, and the presence of impurities.

2. State of matters

   • Solid
     • They are together.
   • Liquid
     • They are as combined and as in solid together but with the difference that they are a little separated from each other.
   • Gas
     • Spread out.
   • Plasma

3. is a particle that was thought when it was created to be uncuttable but is very difficult to cut it though and also they are very small.

4. They are conformed by Neutron Electrons. Protons
