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.
To figure out how many atoms of copper you get in 1 gram of copper, you need to use copper's molar mass. An element's molar mass tells you what the mass of one mole of that element is. Now, one mole of an element is defined as 6.022 * 10^(23) atoms of that element - this is known as Avogadro's number.
