WebSep 19, 2024 · The reactivity of the heavier group 15 elements decreases down the group, as does the stability of their catenated compounds. In group 15, nitrogen and phosphorus behave chemically like nonmetals, arsenic and antimony behave like semimetals, and bismuth behaves like a metal. The stability of the +5 oxidation state decreases from … WebNitrogen and Phosphorus are non-metals, Arsenic and Antimony are metalloids and Bismuth is a metal. These changes can be attributed to the decrease in Ionization enthalpy and increase in atomic size. Boiling points also, in general, show an increasing trend as you move down. Except for Nitrogen, all the other elements have allotropes. 6.

WebOnly nitrogen does not have allotropes. Others have their allotropes. Nitrogen is colourless; Phosphorus is red or violet; Arsenic is dull grey colour; Antimony is silver, and bismuth is a silver-white metal. Phosphates are very reactive. So, they are kept underwater to prevent the flame up. The boiling point also increases as we move down the ...
Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials.
