Question

Statement 1: If an orbit has 8 electrons, then it will be the outermost orbit of that atom.
Statement 2: The outermost orbit of the atom always has 8 electrons.

• A. Only Statement 1 is true.
• B. Only Statement 2 is true.
• C. Both Statement 1 and Statement 2 are true.
• D. Both Statement 1 and Statement 2 are false.

Answer 1

The correct option is D Both Statement 1 and Statement 2 are false.

There can be 1, 2, 3,......., 8 electrons in the outermost shell. Any orbit can have maximum of 8 electrons but not the other way around.For example: Sodium, the electronic configuration of it is 2, 8, 1. It has 8 electrons in second orbit but it is not the outermost orbit. The outermost orbit in this case has 1 electron.
