What atom has 32 neutrons?
Cobalt
How do you find the number of neutrons?
Subtract the atomic number from the atomic mass. Since the vast majority of an atom’s mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom.
What atom has 32 protons 48 neutrons?
Germanium is a chemical element with the symbol Ge and atomic number 32.
Which two atoms are isotopes of one another?
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes.
What are 2 examples of isotopes?
Isotope Examples Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth’s crust. Both have long half-lives.
What are the two main types of isotopes?
Isotope Facts All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive).
What are 3 examples of isotopes?
The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
Is carbon 14 a radioactive isotope?
Carbon-14, which is radioactive, is the isotope used in radiocarbon dating and radiolabeling.
What is the difference between carbon 12 13 and 14?
Carbon 12, 13 and 14 are carbon isotopes, meaning that they have additional neutrons: Carbon 12 has exactly 6 protons and 6 neutrons ( hence the 12 ) Carbon 13 has 6 protons and 7 neutrons. Carbon 14 has 6 protons and 8 neutrons.
How can isotopes be produced?
Radioisotope production in reactors is based on neutron capture in a target material, either by activation or generation of radioisotopes from fission of the target material by bombardment with thermal neutrons.
What are the 3 types of nuclear change?
Nuclear Reactions
- Fission.
- Fusion.
- Nuclear Decay.
- Transmutation.
Why are radioisotopes dangerous?
Breathing in radioisotopes can damage DNA. Radioactive isotopes can sit in the stomach and irradiate for a long time. High doses can cause sterility or mutations. Radiation can burn skin or cause cancer.
What is the heaviest stable isotope?
The heaviest nucleus considered to be stable is now lead-208 and the heaviest stable mononuclidic element is gold as the 197Au isotope. Theory had previously predicted a half-life of 4.6×1019 years. The decay event produces a 3.14 MeV alpha particle and converts the atom to thallium-205.
What is the most stable heavy element?
uranium
What is the longest half life?
18 billion trillion years
What material has the shortest half-life?
Uranium-234 has the shortest half-life of them all at 245,500 years, but it occurs only indirectly from the decay of U-238. In comparison, the most radioactive element is polonium. It has a half-life of a mere 138 days.
What has a half-life of 33 years?
Experiments have shown that proton decay, if it occurs, must have a half-life in excess of 1033 years, more than 50 trillion times longer than that of bismuth and 72 billion trillion times the present age of the universe. You may wonder which naturally-occurring element has the shortest half-life.
