Convalent Bonding Flashcards
True or false. Covalent bonding occurs between elements of very different electronegativities
False, it occurs between elements with similar electronegativities
How is a covalent bond formed
When a pair of electrons from the outer energy levels of each atom are shared. They have opposite spins.
In purely covalent molecules of one element, how are the electrons shared
Equally, the electrons will spend the same amount of time in both orbits
In molecules with varied electronegativities, how are the electrons shared
The electrons spend more time in the orbit of the element that has the greater electronegativity
How is a dipole formed in a covalent molecule
When the electrons spend more time in the orbit of one element than the other, it makes that end of the compound a little negative and the other a little positive. This is a dipole.
