the noble - gas notation for tin (sn) will contain the symbol\nar\nkr\nxe\nrn
Answer
Brief Explanations:
Tin (Sn) has an atomic number of 50. The noble - gas notation uses the symbol of the nearest noble gas with a lower atomic number to represent the inner - shell electrons. Krypton (Kr) has an atomic number of 36 and xenon (Xe) has an atomic number of 54. Argon (Ar) has an atomic number of 18 and radon (Rn) has an atomic number of 86. The nearest noble gas with a lower atomic number than tin is krypton. So the noble - gas notation for tin will start with [Kr].
Answer:
B. [Kr]
