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 alkaline earth metals have an atomic number two higher than the atomic number of the preceding period's noble gas. For example, magnesium is in the third period. The second period noble gas is neon, which has an atomic number of 12. Thus you can determine that magnesium's atomic number is 12. To figure out the one you are interested in, the eighth period alkaline earth metal, first look to the seventh period's noble gas.
