What has 27 protons and 32 neutrons?
The element cobalt has 27 protons. Since the sum of the number of protons and neutrons in your particular question is 59, the answer to what has 27 protons and 32 neutrons is the particular isotope of cobalt labeled 59Co. This is cobalt's only stable isotope.
Symbol for liquid oxygen?
O is the symbol for oxygen it doesn't matter if it is plasma solid liquid or gas
How is radioactivity used in agriculture?
The increase in the volume and quality of grains and cereals has been vastly improved by selectively growing superior strains labeled by radioactive isotopes. These improvements are helping to alleviate famine in third world countries.
What is the mass of a liquid labeled?
It is labeled g.

Produce labeled as 100 percent organic must be organic in the U.S.
What kind of molecule must be labeled to make radioactively labeled DNA?
Radioactive nucleotide

What are you isotope or ion 17 protons 18 electrons 21 neutrons?
The element that has 17 protons is Chlorine, or Cl. The particular isotope of Cl that has 21 neutrons is called 38Cl, and is radioactive, having a half-life of 37.24 minutes. In this particular case, the number of electrons of this isotope are greater than its number of protons by one. That means that this isotope is also an ion, and is labeled as 38Cl-.
