That is, if you stream 1,000 tracks in a day, so your charges are 85p, but you have revenues of 86p, then you have to pay the MCPS 8.6p, not 85p. This seems bonkers to me, and I did ask the MCPS/PRS if I had it right. They seemed to think I had. Musically points to the headline royalty rate.
Use your Periodic Table to determine whether an element is a metal or a non-metal and how many valence electrons it has to help determine if it will bond by transferring (ionic/electrovalent) or sharing (covalent) valence electrons.
The weight of an atom of any given element depends on the number of protons (and neutrons) in its nucleus, but the number of protons also determines the number and arrangement of electrons that can orbit the nucleus, and it is these outer shells of electrons that largely determine the element's chemical properties.
