Chp 5 5.3 Covalent Bonding Flashcards
1
Q
How would a dative bond work when reacting H+ with H2O?
A
As the oxygen in H2O has 4 lone pairs of electrons they can be shared with H+ to complete H+
2
Q
What is the definition of a covalent bond?
A
The electrostatic attraction between the atoms shared electrons and the nuclei of the atoms
3
Q
How can BF3 exist? (Boron has 3 and F has 7 outer electrons)
A
Due to the expansion of the octet, not all atoms have to have 8 electrons on their outer shell as long as they have sufficient bonds
4
Q
Why does carbonate have a charge of -2
A
It has 2 oxygen atoms with on 7 electrons so they are donated 2 electrons giving the charge
5
Q
Describe the force of attraction in a covalent bond?
A
A localised force of attraction in the overlap of the bond
