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 hardest metal is chromium.Actually, hardness is determined by the resistance of the material to be scratched . The hardest material is diamond,then comes corundum etc.This hardness is measured on Mohs scale.People get confused that Osmium has the better claim, but actually it is the densest .
