both ways are correct,but NH3 is well know now.
It is the chemical formula for ammonia. It stands for 3 Hydrogen atoms bonded to 1 Nitrogen atom. It can also be written as NH3 and is sometimes called hydrogen nitride (among other names).
Generally speaking writing hydrogen first in a chemical formula implies that the compound will, in some manner, act as an acid
The name of the common base NH3 is ammonia.
It forms Ammonia, which is possibly H3N.
