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.
Hence, it is the atomic number alone that determines the chemical properties of an element; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number. New elements. The quest for new elements is usually described using atomic numbers.
