Question

[tex]_{17}X^{35} is a gaseous element. Its atomic number is 17. Its mass number is 35.
Find out the number of electrons, protons and neutrons.

Answer 1

The atom's protons is the same as its electrons and same as its atomic number, which is 17.

And for neutrons substract 17 from Its mass number 35. so the neutrons number is (35-17)= 18.

so, number of electrons is 17, protons is 17 and neutrons is 18.
