WebJul 4, 2016 · The correct order of melting point of alkali metal halides is: M F > M C l > M B r > M I. M I > M B r > M C l > M F. M C l > M F > M B r > M I. M I > M F > M C l > M B r. The correct answer to this is option (1), the reason I could think of is that as the size of anion in ionic compound increases the covalent character increases and hence the ... WebExplain the following difference: the melting and boiling points of alkali metals decrease down the group whereas those of halogens increase down the group. Question. thumb_up 100%.

WebNov 4, 2024 · Properties: The melting point of francium is 27 °C, its boiling point is 677 °C, and its valence is 1. It is the second-least electronegative element, following cesium. It is the second rarest natural element, following astatine. Francium is the heaviest known member of the alkali metals series. It has the highest equivalent weight of any element and is the … WebThe group 1 elements are the so-called alkali-metals. The bonding between the atoms is caused by the interaction of the nuclei with the delocalized electrons. With increasing number of electrons and protons, the atomic radii get bigger and hence this interaction becomes weaker as the average distance between nuclei and electrons increases as ... how to measure compartment syndrome
[Solved] The boiling points of Alkali metal group 9to5Science
WebWhat exactly does the melting and boiling points of alkali metals mean? General properties of the group. Metals are ductile, conductive, lustrous, and malleable. An alkali metal’s … Trends in melting and boiling points. The figure above shows melting and boiling points of the Group 1 elements. Both the melting and boiling points decrease down the group. When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. WebAug 12, 2024 · The Group 2 metals have a particular name: the alkaline earth metals. The name is derived from the observation that they have such high melting points (Table \(\PageIndex{4}\).1) that they remain solids (earths) in a fire. Table \(\PageIndex{4}\).2 lists the derivation of the names of the alkali metals. how to measure company success
