Atom of an element has 55 electrons; calculate how many electrons does it have at its outer shell.

Atom of an element has 55 electrons; calculate how many electrons does it have at its outer shell. Show electronic configuration of the element.

Expert Solution

The element here us Caesium.

Electronic Configuration-

1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6 6s^1

Outer shell, ie 6s has one electron.
