Which statement is true?

metals have 5 to 8 electrons in their outermost shell and will easily give them up.

metals have 1 to 3 electrons in their outermost shell and will easily give them up.

metals don't have electrons.

metals have 1 to 3 electrons in their outermost shell and will seek more electrons rather than give any up.

Option (b) is the correct answer.

Explanation:

It is known that metals are rich in electrons and in order to gain stability they readily lose electrons so  that their octet becomes complete.

For example, sodium is a metal and its atomic number is 11. It readily loses one electron to gain stability.

Also, it is easy for metals to lose 1 to 3 electrons from their outermost shell.

Thus, we can conclude that metals have 1 to 3 electrons in their outermost shell and will easily give them up.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
