♥ 1) why does calcium still lose 2 electrons if it has full valence shells? 2) why are protons almost always equal to neutrons? 3) what is the order of chemical formulas? i think the positive charge element is first, and second is the negative charge. 4) i understand the naming of ionic bonds, but what is the full list of prefixes, and suffixes. e.g.: monoxide, dioxide, etc 5) how do i say a chemical formula if it has more than two pure substances? 6) do you always need to have the roman numerals when you are writing chemical formulas like you say it in words? for number five, here is an example: hclo4 would i say it as hydrogen chlorine oxide? or hydrogen chloride oxide? also, for number one, i was taught that the fourth valence shell's capacity is 2. what is the actually capacity.
