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.
A sample of an element contains only one kind of atom in the sample. Suppose you had a lump of copper in your hand. The ONLY type of atom in the lump is copper. In the lump there are trillions and trillions and trillions of copper atoms. NOTHING else.
