3 Minerals – An Introduction to Geology
3.2 Formation of Minerals Minerals form when atoms bond together in a crystalline arrangement. Three main ways this occurs in nature are: 1) precipitation directly from an aqueous (water) solution with a temperature change, 2) crystallization from a magma with a temperature change, and 3) biological precipitation by the action of organisms.
Ionic Bonding | Chemical Bonding | Siyavula
Ionic bonding takes place when the difference in electronegativity between the two atoms is more than \(\text{1,7}\). This usually happens when a metal atom bonds with a non-metal atom. When the difference in electronegativity is large, one atom will attract the shared electron pair much more strongly than the other, causing electrons to be transferred to the atom with higher electronegativity.
