What is the difference between technetium-99m and technetium-99?
Technetium-99m is a metastable nuclear isomer of technetium-99. Technetium-99m is commonly used in medical imaging due to its short half-life and ability to emit gamma rays, while technetium-99 is a radioactive isotope with a longer half-life that is used for various medical and industrial applications, such as in radiopharmaceuticals and nuclear medicine.
If technetium-98 has 55 neutrons how many does technetium-99 have?
Tc has 55 neutrons, its variants such as Tc-99 have a differing number of neutrons ranging from 54, 55, and 56 in the longer lived isotopes such as Tc-99. Tc-99 also has a half-life of 211,000 years.
What are the disadvantages of Technetium 99?
technetium-99 need to be made in a reactor as so this all cost money to do it. by saying that its main disadvantages are high costs and generation of large quantities of highly radioactive waste.
What is the element of the atomic number 43?
Technetium. All atoms of Technetium have 43 protons in their nulceus (this is the meaning of atomic number). In addition, Technetium atoms may have any thing from 50 to 56 neutrons depending upon the isotope.
If an atom decays by gamma decay Which atom is left after the decay?
14 7 N
What is Technium 99?
I suspect you mean technetium 99. Technetium is a radioactive element (atomic number 43 on the periodic table). It is the lightest element with no stable isotope, and as such is used frequently in medicine. See the Wikipedia article for more details.
