When a metal combines next to a nonmetal, what form of bond forms?
Answers:
electrovalent bond
Ionic
Ionic (electrovalent) bonds are formed because the nonmetal, which has a high electronegativity steals electrons from the metals to stuff up their valence electron shell, as well as deplete the metal's valence electron shell so that it to will have an outer electron specifically completely full.
For example: Na and Cl, a common ionic bond from Na (metal) and Cl (non-metal). Na has one electron within its outermost shell, and if it is transfered, its electron configuration will be 2-8, meaning the outermost shell will now be full next to 8 electrons. Cl has seven valence electrons + 1 from the Na if it is bonded (transfered), which fills to 8 as powerfully.
NaCl can be distinguished from a metallic bond since it can only conduct electricity in a fluid phase, where electrons are mobile. Positive Ions are called "cations" and denial ions are called "Anions". Source(s): Chemistry teacher- I was told to remember "cation" by
ca + ion <- Positive ion
a n ion <- "A Negative Ion"
