WebReactivity depends on the loss of the outer electron, and so it increases down the group, because the outer electron is less firmly held as you go down the group. Predicting the properties of francium. Because francium is very radioactive with only a short existence, nobody is going to be able to check most of this, but you can make predictions. WebAt 298 K, the solubility product constant for PbC2O4 is 8.5 1010, and the standard reduction potential of the Pb2+(aq) to Pb(s) is 0.126 V. (a) Find the standard potential of the half-reaction PbC2O4(s)+2ePb(s)+C2O42(aq) (Hint: The desired half-reaction is the sum of the equations for the solubility product and the reduction of Pb2+.

WebJul 20, 2024 · Francium (Fr) is quite radioactive, and only small quantities are available for study; so it too is usually omitted. Its properties, however, appear to be similar to those of … WebAug 21, 2024 · The Reactions with Oxygen. Group 1 metals are very reactive, and must be stored out of contact with air to prevent oxidation. Reactivity increases as you go down the group; the less reactive metals (lithium, sodium and potassium) are stored in oil (because of its density, lithium floats in oil, but because it is less reactive than the other metals in the … WebZinc, Palladium, Tungsten, Francium; 30. which of the following is the correct arrangement of given metals in ascending order of their reactivity zinc iron magnesium sodiuma. zinc》iron》magnesium》sodiumb. sodium》magnesium》iron》zincc.sodium》zinc》magnesium》irond.sodium》magnesium》zinc》iron dynan construction sarasota
