Chlorine has two stable isotopes chlorine-35 and chlorine-37with Chlorine-35 accounting for roughly 3 out of every 4 naturally occurring chlorine atoms. Chlorine-36 is also known naturally and is a radioactive isotope with a half life of about 30,000 years.
Answer to: An atom of chlorine-37 has: - 37 neutrons and 17 protons. 17 protons and 20 neutrons. 17 neutrons and 37 protons. For Teachers for Schools for Working Scholars.
What is the difference between the number of electrons in an atom of Tin (Sn) which has an atomic number of 50, and the number of electrons in an atom of Chlorine (Cl) which has an atomic number of 17. There is no difference. There is not enough information to.

Explanation:

Your tool of choice here will be chlorine's electron configuration.

Chlorine, #'Cl'#, is located in period 3, group 17 of the periodic table, and has an atomic number equal to #17#. This tells you that a neutral chlorine atom will have a total of #17# electrons surrounding its nucleus.

Chlorine's electron configuration looks like this

#'Cl: ' 1s^2 2s^2 2p^color(red)(6) 3s^2 3p^color(green)(5)#

Now, notice that the first energy level doesn't not contain a p-subshell, and implicitly any p-orbitals.

The second energy level, on the other hand, contains two subshells, the 2s-subshell, which contains #2# electrons, and the 2p-subshell, which contains three 2p-orbitals and a total of #color(red)(6)# electrons, #2#per orbital.

Finally, the third energy level contains two occupied subshells, the 3s-subshell, which once again contains #2# electrons, and the 3p-subshell, which contains #color(green)(5)# electrons.
