Electron transfer is the term for this process. The resulting anion and cation are attracted by...
Electron transfer is the term for this process. The resulting anion and cation are attracted by Coulombic forces and an ionic compound is formed. Ionic compounds are neutral: the number of electrons lost in forming the cation(s) must equal the number gained in forming the anion(s). For example, Aluminum (Al, Z = 13, Group 3A or 13) will lose 3 electrons to become Al3+ which is isoelectronic with Neon (Ne), its closest noble gas. To form an ionic compound those...

A. If the following elements were to form an
ionic compound, which noble-gas configuration would they most
likely attain?
Drag the appropriate elements to their respective bins.
B. An unknown element, X, reacts with lithium
to form the compound Li2X. In other compounds this element also can
accommodate up to 12 electrons rather than the usual octet. What
element could Xbe?
