Chemistry 2.2.6: Covalent Bonding Flashcards
1
Q
what is covalent bonding?
A
an electrostatic attraction between a shared pair of electrons and the nuclei
2
Q
what is a lone pair?
A
a pair of electrons in the outer shell that are involved in bonding
3
Q
what is average bond enthalpy?
A
measure of average energy needed to break the bond, the larger the the value of the average bond enthalpy the stronger the covalent bond
4
Q
what is a double bond?
A
bonding involves the sharing of two pairs of electrons
5
Q
what is a triple bond?
A
bonding involves the sharing of three pairs of electrons
6
Q
