Science Part 1

1. What is Matter ?

   • Is everything that in a certain region of space and time has the energy and is composed of changes over time
     • Phases of Matter ?
       • The phases of matter are top much but the four most important are Solid , Liquid, Gas, and Plasma that are conformed by particles

2. What is an Atom?

   • An Atom is the smallest particle of a chemical element that had been exist
     • The main models were the Thompsom, Bohr,Dalton and Ballard Ball Model.
       • The first Scientific was Democratuis to think an idea about atoms

3. Bolding and Periodic Properties

   • Are specific pattern in properties of chemical elements
     • Can be the gas , liquid or melting point

4. Periodic table

   • In the periodic table is The elements in a group have similarities in the electronic configuration of their atoms, and thus they exhibit somewhat related physical and chemical properties and a period is All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods
     • Group
