Ionic Bonding Question

[Emily_Stenzler_2H]

I believe this was in lecture but I somehow missed it and can't find it anymore so I just wanted to confirm-
elements on the periodic table that are further apart from each other are more likely to form an ionic bond, correct? From my understanding, these elements would have very different electron affinities which would make them more likely to form ionic bonds. Please let me know if this is correct! Thanks!

Yeah, that's right. The nonmetals on the rightmost side of the periodic table are more likely to lose electrons while the metals on the left side are more likely to gain electrons. Thus, when the nonmetals and metals make a compound, they will have a complete electron transfer to make an ionic bond.

[Marley Magee 3A]

I think you might have that backwards. It was my understanding that the nonmetals are the ones that gain electrons while the metals lose them, making the nonmetal the anion and the metal the cation.

Yes, ionic bonds are typically formed by elements from two sides of the periodic table. Different types of bonds between atoms are determined by their difference in electronegativity, halogens usually have very high electronegativity so they gain electrons and metals have low electronegativity therefore they lose electrons.

The elements in groups 1 and 2 have a lower electron affinity and therefore want to lose electrons and become cations. The elements on the far right side of the periodic table have a much higher electron affinity and want to gain electrons in order to form an octet, so they are likely to form ionic bonds with the metals on the left side of the periodic table.

The elements on the right (nonmetals) gain electrons, becoming anions (negatively charged). The elements on the left (metals) lose electrons, becoming cations (positively charged). This is because the nonmetals are more electronegative than metals, meaning they hold onto their electrons more tightly. One way I use to remember this is that anion starts with "an" as in "a negative" and anions are negatively charged.

The elements on the right are nonmetals, which are very electronegative due to their closeness to the noble gases. This causes them to gain electrons, becoming anions (negative). The elements on the left are metals, which are less electronegative since they can get closer to noble gas valence electrons by losing electrons, becoming cations (positive).
