The elements potassium (K) and chlorine (CI) can form an ionic bond. Which of the following
statements correctly explains what occurs (in this ionic bonding)?
1.) As chlorine has 7 valence electrons, it tends to form bonds to gain one electron (to get a full valence shell of 8).On the other hand, potassium has one valence electron, so it tends to lose this electron to other atoms (and
become a cation)
2.) As chlorine has 7 valence electrons, it tends to form bonds to lose all 7 electrons. On the other hand,potassium has one valence electron, so it tends to gain 7 electrons (to get a full valence shell of 8).
3.) In this ionic bonding, potassium is the anion and chlorine is the cation.
4.) During the ionic bonding between potassium and chlorine, 8 electrons are shared between these 2 atoms.

Answer:

As chlorine has 7 valence electrons, it tends to form bonds to gain one electron (to get a full valence shell of 8).On the other hand, potassium has one valence electron, so it tends to lose this electron to other atoms (and

become a cation)
