Boiling point of group 15 elements
WebAnswer: Just like its next door neighbour, water, it’s because of hydrogen bonding. However, as water has two hydrogen atoms per molecule and two lone pairs, it is able to link together far more molecules than ammonia that has a 3:1 hydrogen/lone pair ratio, hence water’s much higher boiling poin... WebJul 12, 2024 · 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 …

WebSo, down the group 15 and 16, as molecular mass increases, melting and boiling point should also increase but melting and boiling point of antimony is more than that of bismuth. (even though molecular mass of bismuth is more) Similarly, melting and boiling point of tellurium is higher than polonium. Why is it so?
WebThe zero point is different: temperature (K) = temperature (°C) + 273.15. Thus, the melting point of water is = 0°C = 273.15 K and the boiling point of water is = 100°C = 373.15 K. On the Fahrenheit scale (°F), the melting point of water = 32°F while the boiling point = 212°F. Therefore the degree size is different on the Fahrenheit scale ... freestanding bathroom furniture ukWebApr 5, 2024 · For example: NH 3 being most stable among the group 15 hydrides is not a good reducing agent.
