78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide and small concentrations of other elements. <span />
If you mean lewis dot symbol you need a nuclide you get the number of proton (z) its equal to electrons since the atom is nutral then you make the elctron configuraion after that you take the number of electrons on the outer energy level( ex:k²L² in this case its the 2 on the L)and if you have 7 electrons and the atom is nitrogen so it becomes

Answer:
a. The atom will go from a two-dimensional configuration to a three dimensional configuration.
d. The bond angle will increase.
f. The number of unhybridized p orbitals will decrease.
Explanation:
Sp2 is the atomic bond in which orbitals mixes with only two orbitals. These orbitals form three sp2. When two carbon atoms are overlapped they form sigma bond by overlapping of sp2 bonds. Sp3 bond is created when there is one lone molecule available for combination. When the bonding is updated from sp2 to sp3 then unhybridized orbitals will decrease causing the bond angle to increase.
Answer:
The statement that describes the advantage of a nonrenewable energy source is that ' they are currently found in abundance' Option D.
Explanation:
Nonrenewable energy sources are sources of energy which will not be replenished after their use, their production usually takes millions of years to be accomplished, Like crude oil, the synthesis under the ground was believed to take Millenium from the various geothermic reactions that occur on the buried biomass millions of years ago.
However, since these energy sources are liable to be exhausted quickly due to their unreplenish nature, nature provides them in abundance. They are currently found in large quantity. Take for example, the coal deposit and crude oil wells which had been mined for many years before now. The continuous usage of these nonrenewable sources nevertheless makes them to be susceptible to exhaustion in some years to come.
