A Lewis structure or dot electron structure is a representation of an atom in which the valence electrons on the outermost shell of the atom are represented as dots.
These dots show the number of valence electrons as well as the group to which the atom belongs in the periodic table.
Answer:
D) energy required to remove a valence electron
Explanation:
Ionization energy can be defined as the atom's ability to and the energy required to remove a valence electron. Ionization energy increases up a group and to the right along a period. So helium has the highest first Ionization energy meaning that it is very hard to remove an electron from helium because octet is already complete.
