Why is the melting point of sulfur higher than that of phosphorus?

Although they are both molecular structures, sulfur exists as S8 while phosphorus exists as P4. Sulfur has more electrons, therefore also has more Van Der Waals forces, than phosphorus. This means that it will require more heat energy to overcome these forces, causing it have a higher melting point.


What is the similarity and difference between sulfur and lithium?

SimilaritiesBoth lithium and sulfur are elements that can be found on the periodic table.Both lithium and sulfur are solids at room temperature.Both lithium and sulfur have very high melting/boiling points.DifferencesLithium is a metal. Sulfur is a non-metalLithium is lustrous (shiny) in appearance. Sulfur is not.Lithium is a good conductor of electricity and heat. Sulfur is not.Lithium is malleable (able to be hammered into different shapes) and ductile (able to be draw into a wire). Sulfur is brittle.In chemical reactions, lithium tends to lose electrons whereas sulfur tends to gain electrons.Sulfur has a greater electronegativity (affinity to electrons) compared to lithium.Sulfur has a larger atomic radius than lithium.The 1st ionisation energy (minimum energy required to remove the first electron from the valence shell of a gaseous atom) of sulfur is greater than that of lithium.

Does Plants need both sulfur and phosphorus in order to grow and reproduce How do plants obtain sulfur and phosphorus?

Sulfur and Phosphorus are available to a small degree naturally in the soil. When they are depleted they can be added through fertilization or crop rotation. These traces are necessary for proper growth.
