Bonding 6 (covalent Bonds) Flashcards
Covalent bonds form when two or more atoms want to
Share electrons
(Covalent bonds) the sharing must allow for all the atoms to
Obtain a full octet
Covalent bonds occur mostly between _ that are close to each other on the periodic table
Nonmetals
Reason why covalent bonds occur mainly between atoms close to each other on the table
Similar electronegativity
Elements will have similar electronegativity aka
Both want to gain electrons
(Covalent bonds) in order to form an ionic bond, carbon would have to gain or lose
Four electrons (a lot)
(Covalent bonds) not only would carbon have to gain or lose 4 electrons
But it would have to find another element that would need to do the same
_ is not very likely
4 and 4 combo
(Covalent bonds) to solve 4 and 4 problem, carbon
Shares its electrons with another atom
Properties of covalent bonds (low 2)
Melting point
Boiling points
Only covalent bonds without low melting and boiling points
Network covalent bonds
Properties of covalent bonds (softer than)
Ionic bonds
Covalent bonds don’t (2)
Conduct electricity
Dissolve into water
Covalent bonds are more _ than ionic compounds
Flammable
Easiest way to see how covalent bonds work is to look at _ diagram
