Loess to form very fertile soil. select the best answer from the choices provided t f

The given statement is true.  

A classic, predominantly silt-sized sediment, which is produced due to the gathering of wind-blown dust is known as loess. About 10 percent of the land region of the Earth is covered by loess or identical sediments. The loess seems to form into very rich soils. Under suitable climatic circumstances, it is one of the most agricultural productive terrains around the globe.  

The soils formed by loess seems to be extremely drained. It is considered that the fertility of the loess soils is mainly because of porosity and cation exchange capacity.  

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
