Periodic Table Box of an Atom
4
Nucleus

• very dense region consisting of protons and
  neutrons at the center of an atom (mass)

5
Proton

• stable subatomic particle in all atomic nuclei,
  with a positive electric charge

6
Neutron

• a subatomic particle without an electric charge,
  present in all atomic nuclei except hydrogen.

7
Electron Orbital

• the path of an electron around the nucleus of an
  atom

8
Electrons

• A subatomic particle with a negative charge but
  zero MASS

9
Atomic Number

• the number of protons in the nucleus of an atom
• determines the chemical properties of an element
  and its place in the periodic table.

Mass Number

• the total number of protons and neutrons in a
  nucleus.
• Gives the atom weight or mass

13
Element Symbol

• A chemical symbol is a 1-, 2-, or 3-letter
  internationally agreed code for a chemical
  element, usually derived from the name of the
  element, often in Latin. Only the first letter is
  capitalized. For example, "He" is the symbol for
  helium, "Pb" for lead, "W" for tungsten.

14
Element Name

• The full name of the element usually located
  under the element symbol on a periodic table

15
State of Matter

• A symbol used on the periodic table to indicate
  if an element is in the SOLID, LIQUID or GAS
  state at room temperature.

16
Atom

• the basic unit/building block
• of a chemical element.
