It varies greatly depending on tenure, job, and rank. A private E1 will make about $18,000 in a year. A general O10 can make upwards of $234,000 per year.
In the US Military there is Rate (called many things, such as MOS), Rank, and Pay Grade. Pay Grade is E1-E9 (Enlisted), W1-W5(Warrant Officer), O1-O10 (Commissioned Officer).

If you mean do the exist as single atoms, no. Some can exist as molecules. Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine usually exist as the diatomic molecules H2, N2, O2, F2, Cl2, Br2, and I2 respectively. Oxygen can also exist as O3. Phosphorus can exist as P4 and arsenic as As4. Sulfur is usually found as S8. Carbon can exist as C60 and a variety of similar molecules.
When a second phosphate group is added its makes adenosine diphosphate AKA (ADP).
draw a triangle & its exterior angle on one side and name he exterior angle as4 and interior opp. angle as 1 and 2 and name the third angle as 3 now we know exterior angle is equal to the sum of interior opp. angle so,angle1+angle2=angle 4 we also know angle3+angle4=180(linear pair) NOW from this 2 equation angle1+angle2+angle3=180
