WebAug 18, 2024 · Trends in melting and boiling points 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. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond.

WebTrends in Group 2 Compounds. Group 2 Elements are called Alkali Earth Metals. They are called s-block elements because their highest energy electrons appear in the s subshell. Progressing down group 2, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. WebIt has a melting point of 248 °C, a boiling point of 300-400°C, a molar mass of 106.44 g/mol, and a density of 2.49 g/cm.³ It is stable at room temperature and highly soluble in water. It is a strong oxidizing agent and bleach, which is used as an intermediate in the production of chlorine dioxide. children\u0027s books about sound
