It's no trouble

Explanation:

Electronic configuration of fe=1s2,2s2,2p6,3s2,3p6,4s2,3d6

e.c of fe3+=1s2,2s2, 2p6, 3s2, 3p6, 4s0, 3d5

e.c of S= 1s2,2s2, 2p6, 3s2, 3p4

e.c of s2-=1s2, 2s2, 2p6, 3s2, 3p6

Iron or Iron is the first element of the eighth group of the periodic table. This is the most attainable element in the womb and outside of the womb. This is the fourth most commonly found element in Earth's womb. It has four permanent isotopes, whose mass is 54, 56, 57 and 58.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
