Answer 2

There are a total of 10 's' electrons in a neutral atom of Sn. (option 2)

• Tin (Sn) is a soft, silvery metal element belonging to the 5th period and 14th group of the periodic table.
• It has an atomic number of 50 and hence 50 electrons in its shells. Its electronic configuration can be written as- 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p².
• Each 's' subshell has maximum of 2 electrons. Tin has five completely filled 's' subshells and thus 5×2 = 10 's' electrons.
