How many isotopes are there of (a) hydrogen (b) chlorine (c) carbon (d) uranium
ALSO NAME ALL ISOTOPES
Answers
Explanation:
(A) Hydrogen : 3
EXPLANATION :
Hydrogen has three naturally occurring isotopes: 1H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H) have been synthesized in the laboratory, but do not occur in nature.
(B) CHLORINE : 2
EXPLANATION:
Chlorine has two stable isotopes and about 24 isotopes in total (most are unstable). The two principal stable isotopes are 35Cl (75.78%) and 37Cl (24.22%), giving chlorine a standard atomic weight of 35.45.
(C) CARBON : 3
EXPLANATION :
There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers - 6, 7, and 8, respectively - all differ.
(D) URANIUM : 3
EXPLANATION:Naturally occurring uranium consists of three isotopes: uranium-234, uranium-235 and uranium-238. Although all three isotopes are radioactive, only uranium-235 is a fissionable material that can be used for nuclear power.
