What is that symbol? Well, it is that time of the semester when you get to start memorizing the symbols and the names of the elements. Get ready, here we go: H He Li Be B C N O F hydrogen (exists in nature as H2) helium lithium beryllium boron carbon nitrogen (exists in nature as N2) oxygen (exists in nature as O2) fluorine (you’ll FLunk if you write Fl. And it is fluorine, not flourine. We’re not baking cookies.) (exists in nature as F2) Ne neon Na sodium Mg magnesium Al aluminum Si silicon P phosphorus (P is for phosphorus, not potassium) S sulfur (S is for sulfur, not sodium) Cl chlorine (make sure you can recognize Cl as chlorine. Students will often confuse chlorine and call it carbon iodine. Cl is NOT carbon iodine) (exists in nature as Cl2) Ar argon K potassium Ca calcium Zn zinc Pb lead Fe iron Cu copper Au gold Ag silver Mn manganese Ni nickel Co cobalt Br bromine (exists in nature as Br2) I iodine (exists in nature as I2) Fr francium Hg mercury Rn radon Ra radium Sn tin Study hint: make flash cards. Put the symbol on one side of the card and the word on the other side of the card. Use sheets of paper if index cards are not available. You will be responsible for knowing these names and symbols on all tests. You might receive another list later, but for now this will do.
