text: Pull out your periodic table (I would but I don't have one anymore)...\n\nRemember to answer practically every question you have listed, just remember these two facts:\n\nThe Atomic number of an Element = the number of protons.\n     and the number of protons = the number of electrons.\n\nThe number of neutrons in an Element = the atomic weight - the atomic number (i.e. the number of protons)\n\nAnd last hint:  The number of neutrons is usually close to the number of protons give or take a few.\n\nSo to answer the first question:  Find two elements with an atomic number close to 10, and you'll probably find the ones with 10 neutrons.\n\nThe second question (I'll give you this one since I don't need a periodic table for this one) :p  \n2 protons means the Element has an atomic number of 2 (i.e. He, or helium)\n\nThe third question (I'll give you this one too since I still have this memorized from high school... I think) ;)\n3 electrons means 3 protons means an atomic number of 3 (i.e. Li, or lithium)\n\nYou figure out the rest...  oh except question G... Ferrum...Ferrous... Element Fe... "iron"
