'NO' is not an element, and is therefore not found on the Periodic Table. The chemical NO is nitric oxide (aka nitrogen(II) oxide), a colorless gas at room temperature.
If, however, you are referring to 'No', then it is the symbol for Nobelium, which is a synthetic, metallic, radioactive element with atomic number 102. It can be found in the actinide series.
NO3 means one nitrogen atom combined with 3 oxygen atoms to produce the nitrate ion. NO4 is one nitrogen atom combined with 4 oxygen atoms.
In chemistry Po stands for Polonium
MP usually stands for Melting Point, i.e. the temperature at which a substance turns from a solid to a liquid.
They are used in practical experiments, particularly chemistry, to hold test tubes, burettes etc in position over something else such as a Bunsen burner or beaker.
Properties of stuff is the domain of physics and engineering. The composition of stuff is the domain of Chemistry.
NO3 means one nitrogen atom combined with 3 oxygen atoms to produce the nitrate ion. NO4 is one nitrogen atom combined with 4 oxygen atoms.
Please read your question over, and ask again- but a Mk1 No4 and a Mk1 No4.........???
Brittish made Lee Enfield rifles went through many changes up to and including the No4. The No4 was made close to the end of WWII. The Brittish battle needs shifted to jungle warfair after WWII. The No4 was not well suited for the jungle. The No4 is not very common but is not very rare either.
The symbol NO4 does not correspond to a known chemical species. Nitrogen dioxide (NO2) and nitrate (NO3-) are common nitrogen and oxygen-containing compounds, but NO4 does not have a recognized chemical formula.
In chemistry, "UG" stands for "Uranium Glass."
carbon
Uranium
Sulfur
francium
AgNO3, or NO4...
To manimonzed to money
In Chemistry it stands for Iron
