How are elements on the periodic table arranged?
By Atomic Mass
By Neutrons
By Atomic Number
By Electrons
Carbon (C) has an atomic number of 6. Carbon is next to Nitrogen (N) on the periodic table. Nitrogen has an atomic number of 7. Would it be possible for scientists to discover a new element that will be placed between these 2 elements on the periodic table? Please select the best choice.
Yes, because the letter "C" and the "N" are far apart in the alphabet
No, the elements are in order by atomic number and you cannot have half a proton
Yes, because new things can always be discovered, such as an atom with 6.5 protons.
