Use the information in the table to predict the melting point of francium, Fr ... WebJul 11, 2007 · Francium probably is more immediately reactive with water than caesium is. This is because francium likely has a lower melting point than cesium, so it will be melted by the heat of its reaction with water more quickly. This is what causes alkali metals to become more reactive down the periodic table. In the gaseous state, it is just the opposite. fly fishing japan fiberglass flyrodders

WebFrancium occurs as a result of α disintegration of actinium. Francium is found in uranium minerals, and can be made artificially by bombarding thorium with protons. It is the most unstable of the first 101 elements. … WebThus Caesium is more reactive than Francium. Why is francium the most active metal? Francium is an alkali metal in group 1/IA. All alkali metals have one valence electron. … The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive. 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 … fly fishing italy
