I really need help with thisI'm supposed identify the element with the symbolok here are the questions:1Period 4 with 4 valence electrons270 electrons around the nucleus3Alkali metal that was named after a country4Alkaline metal in period 35Which of the following is not a transition metal: zinc, gold or aluminum Thanks a lotI really need your help.
1Germanium would be the element with 4 valence electrons (limetang, you are thinking of GROUPS, in which all of the elements in the IX A group (C, Si, Ge, Sn, Pb and Uuq) would have 4 valence electronsPeriods are the horizontal rows) 2Ytterbium would be the atom with 70 electrons (as long as it is neutral) 3Everybody has forgotton FRANCIUM (Fr) which is number 87, and the last alkali metal(the six being Lithium, Sodium, Potassium, Rubidium, Caesium, and FRANCIUM) is named after France where it was discovered 4Magnesium is the alkaline earth metal in period 3 5Aluminium is not a transition metal.
Aluminum from cookware can leach into the foodtry something else (non-stick material can also leach)Try Stainless Steel or Pyrex if you can.
it's oxide that's coming off (like tarnish on silver)I don't know if it's bad for you, but you may want to try lining your baking sheet with a silpat instead.
