WebNov 26, 2024 · The electronegativity of Francium is: χ = 0.7 In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. WebFrancium is the least electronegative of all the elements, therefore it should be the most chemically reactive alkali metal. Unfortunately, it is not available in sufficient quantities to show it reacting with water – it is made in tiny …

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. WebReactive, light metals with one valence electron in the outermost shell are known as alkali metals. They are soft, low density metals that have a strong chemical reaction with water. The periodic table's group 1 contains the alkali metals, which are composed of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium.

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.
