Why is the bond between two single hydrogen atoms stable? a. it is not stable, each hydrogen only has 1 electron and they need 8 electrons to be stable. b. hydrogen only uses the first energy shell, which holds 2 electrons, not 8. c. each hydrogen donates more electrons in their lower energy shells to get to 8 but only to other hydrogen atoms. d. each hydrogen has 4 electrons to share for a total of 8 when 2 hydrogens bond.

B. Hydrogen only uses the first energy shell, which holds 2 electrons, not 8.

Explanation:

As hydrogen is the first element in the periodic table and has the atomic number it can mix with a variety of elements, including itself, when two atoms of Hydorgen bond the bond they create fills up the first level of energy which only uses 2 electrons in order to be completed, which makes the bond stable by filling up the energy level.

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.
