What is the maximum number of electrons an orbital may contain?

The maximum number of electrons an orbital may contain is 2 electrons.

Explanation:

There are 4 atomic orbitals called s, p, d and f.

There are one orbital s and it has 2 electrons.

There are three orbitals p, each one contain 2 electrons and in total they have 6 electrons.

There are five orbitals d, each one contain 2 electrons and in total they have 10 electrons.

And there are seven orbitals f, each one contain 2 electrons and the maximum number of electrons this orbital can contain is 14 electrons.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
