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.
Why does the proton determine the identity of an atom? The number of protons is also the atomic mass. The number of protons determines chemical properties, such as reactivity. The number of protons in an atom's nucleus determines an atom's atomic number. The number of protons decides an atom's name.
