ELECTRONS AND BONDING

Question 1

WHAT IS AN ATOMIC ORBITAL

Answer 1

a region around the nucleus that can hold up to 2 electrons with opposite spins

Question 2

ORDER OF ELECTRON CONFIGURATION UP TO 4D

Answer 2

1s 2s 2p 3s 3p 4s 3d 4p 4d

Question 3

WHAT IS IONIC BONDING

Answer 3

the electrostatic attraction between positive and negative ions

Question 4

ELECTRICAL CONDUCTIVITY OF IONIC COMPOUNDS

Answer 4

Not a conductor in solid state as ions aren’t free to move, but once dissolved in water the ionic compound will conduct electricity as the ions are free to move as mobile charge carriers

Question 5

SUMAMARY OF IONIC COMPOUND PROPERTIES

x3

Answer 5

-high melting and boiling points
-dissolve in polar substances
-conduct electricity in liquid state or aqueous solution

Question 6

WHAT IS COVALENT BONDING

Answer 6

the electrostatic attraction between a shared pair of electrons and the nuclei of the bonded aroms

Question 7

what is a dative covalent bond

Answer 7
