The electron removed during the ionization of beryllium ([He]2s 2) is an s electron, whereas the electron removed during the ionization of boron ([He]2s 2 2p 1) is a p electron; this results in a lower first ionization energy for boron, even though its nuclear charge is greater by one proton. Thus, we see a small deviation from the predicted ...

Step-1: To draw the lewis structure for SO2, we have to find out the valence electrons of sulfur and oxygen first.We express valence electrons as dots in lewis dot structure. To get the valence electrons of sulfur,we need to look at the electronic configuration of sulfur. Without its outermost electron, the lithium atom would have more positive charges (+3) than negative charges (-2). An atom with a different number of electrons to protons would be called an ion . Elements like lithium that loose their electrons form positive ions.
