Answer:
Hydrogen
Explanation:
It is considered a special element due to its flexibility in giving up & taking in electrons, therefore making it good for organic & inorganic chemistry. Hydrogen has only one proton and one electron and is the only element which has no neutrons. it is considered as the simplest element in the universe and gives a valid reason for it to be the most abundant and common element in the universe.
Hoped this helped! If this doesn't fit your 80 word count, you could shorten it.

bromine. argon is a noble gas with stable electronic configuration, thus it does not need to gain or lose electrons and will not react to form compounds.</span>
For this system, we use Dalton's law of partial pressures where the total pressure of a gas mixture is said to be equal to the sum of the partial pressures of the gases. The partial pressure of each gas would be calculated by the product of the mole fraction and the original pressure of the gas. We do as follows:
Total pressure = x1P1 + x2P2
Total pressure = (2.0 / 7.0 )(3.5) + (1.5/7.0)(2.6)
Total pressure = 1.56 atm
6 protons, 6 neutrons, and 5 electrons
2) B. Dependent Variable. This is because the rate of the algae growth depends on the other variables. 3) D 4) F 5) C 6) A 7) E 8) B
