Molecular Geometry

Question 1

Covalent bond

Answer 1

A bond which occurs between two atoms which share at least one pair of electrons

Question 2

Valence Electrons

Answer 2

The electrons in the outermost energy level of an atom.

Question 3

Valency

Answer 3

The number of electrons gained, lost or shared to complete the outermost energy level

Question 4

Lone pairs

Answer 4

These are electron pairs in the outermost energy level of an atom that do not take part in the chemical bonding process

Question 5

Ionic Bond

Answer 5

Is defined as z trancefer of electrons and subsequent electrostatic attraction

Question 6

Metalic Bond

Answer 6

Is defined as being between a positive kernel and a sea of delocalised electrons

Question 7

VSEPR theory

Answer 7

Valence Shell Electron Pair Repeltion Theory
Is a modle used, in chemistry, to predict the geometry of indervidual molecules from the number of electron pairs surrounding their central atoms

Question 8

Electronegativiy

Answer 8

Is a measure of the tendency of an atom attract a bonding pair of electrons
