For example, if the ball lies on a cart path, the ball must be dropped at a point where the cart path does not interfere with the lie of the ball, his stance, and also the area of intended swing. If the ball comes to rest in such a position, it must be re-dropped (Rule 20-2c(v)).
Rhodium is a silvery-white transition metal that holds the distinction of being the world's most expensive precious metal. It has an atomic number of 45 and is about as nonreactive as gold. The only way to dissolve rhodium is with sulfuric acid.
Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.Pure radium is almost colorless, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).adium nitrate (Ra(NO 3) 2) is a white compound that can be made by dissolving radium carbonate in nitric acid. As the concentration of nitric acid increases, the solubility of radium nitrate decreases, an important property for the chemical purification of radium.
