Question

acalculate the effective nuclear charge of outermost electron in potassium atom ​

Answer 1

Answer:

Shell 4 where 1 electron originally was becomes 0 when it is a potassium ion. Therefore by removing electron one, the core electrons are the 10 in shell 1 and 2 and 8 is in our outermost shell (not valence). The effective nuclear charge on the outermost electron in a potassium ion will be 9+.
