covalent and ionic bonds

Postby Tiffany Cao 1D » Sat Nov 04, 2017 3:04 pm

When can an element have both covalent and ionic bonds? Or is this impossible?

An element can have either ionic or covalent bonds, but an ionic bond can have covalent character and vice versa.

The types of bonds that elements have is dependent on the other element it is bonding with. For instance, two nonmetals have a covalent bond while a non mental bonded with a metal has an ionic bond.

Also, you can tell whether it will form an ionic or covalent bond by looking at the difference in electronegativities of the two atoms that are bonding. If the difference is greater than 2, it's going to be an ionic bond. But, if the difference between that same atom and another atom is less than 1.5, then it will be a covalent bond. If the electronegativity difference is between 1.5 and 2, then we can't be so sure one way or another.
