As far as i know electrons don't in its own axis they rotate in their orbits 1st orbit can hve 2 electron , 2nd can hve 8 its coz of electronic configuration Electrons have negative charge their charge let them rotate

How would you justify the presence of 18 elements in the 5th period of periodic table ? Explain

Sujatha Vijay 7 years, 5 months ago

We start the 5th period with 4s orbital. We can add 2 electrons in 4s. Then we fill 6 electrons in 4p orbital. Further we start filling the 4d orbital which can take 10 electrons. So in the 4th principal quantum energy stater, we can fill 18 electrons. Thus 5th period has 18 elements.
