Divide page 42 of your IAN Periodic Table Symbols & Numbers TITLE OR
Top Left Corner IAN pg. 42 8 O Oxygen 15.999 ATOMIC NUMBER Atomic Symbol Element name ATOMIC MASS Chemical Symbols will usually be RED = GAS, BLUE=LIQUID or BLACK=SOLID.
Top Right Corner IAN pg. 42 8 15.999 O Oxygen -2 ATOMIC MASS ATOMIC NUMBER Atomic Symbol Element name Ionic Charge Chemical Symbols will usually be RED = GAS, BLUE=LIQUID or BLACK=SOLID.
Bottom of IAN PAGE 42 • Choose 2 elements from your periodic table on page R-7 in your agenda. Pick a solid, and a liquid. Use the table on the wall to make sure you have one of each. • Copy and color each box as it appears in your table. • Label the atomic number, atomic symbol and atomic mass of each element.
I. Atomic Numbers A. The Atomic Number is = to the # of PROTONS or Electrons. 1. The number of protons an element has is the IDENTITY of the atom! ***Always Remember that the Atomic Number is equal to the number of Protons or Electrons.
The Atomic Mass is = to • the number of protonsplus the • number of neutrons. • (Mass # is rounded to get the At. Weight) • Li = 6.941 rounded to 7 • C. Atomic Mass– Atomic # = Neutrons • (Protons + Neutrons) – (Protons) = Neutrons • Ex. CarbonAtomicMass # : 12 (P & N) • Atomic # : 6 P • 6 N - -
II. Symbols/Names A. Atomic/chemical symbols = shorthand version of element name. B. Scientists use chemical symbols, easier to write out
C. Names & Symbols based on Latin name , place or honor a person. Ex. aurum for Gold. (Au) kalium for potassium (K) Ex. Polonium after Poland (Po) Einsteinium for Einstein (Es)
D. One letter Symbol = Capitalized Two letter Symbol = Capital then lowercase. Ex. Sulfur = S, Neon = Ne What would “CO”be? CO = Carbon and Oxygen NOT COBALT = Co
