Question

An atomic caution with the charge of +1 has the following electron configuration:1s22s22p63s23p6What is the chemical symbol for the ion? How many electrons does the ion have? How many 1S electrons are in the ion?

Answer 1

The atomic cation with +1 charge with the following configuration:

1s22s22p63s23p6

Is Potassium (K+), remember potassium have 19 electrons in its neutral state, when if losses one electrons it becomes + with one less electron, meaning it will have 18 electrons as a cation.

There are 2 electrons in 1s orbital as it can be seen from the electron configuration.
