The negative ion F has the same electronic configuration as the positive ion?

The negative ion F has the same electronic configuration as the positive ion Ne. This is because the negative ion F gains an electron to achieve a stable octet configuration, similar to the stable electronic configuration of the noble gas Ne.


What is common to the electronic configuration of Li and K?

Both lithium and potassium have one electron in their outermost energy level (Li: 2-1, K: 2-8-8-1). This similarity in electronic configuration gives them similar chemical properties, particularly in terms of reactivity and the ability to form positive ions by losing their outermost electron.
