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 number of protons determines the number of electrons. This, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide positive charge to the atom. The number of protons also determines the identity of the element. Electrons have a negative charge. Since the atom has no charge, the number of electrons must equal the number of protons. The electrons arrange themselves in energy levels around the nucleus.
