A-Level Physical Chemistry Electronegativity and Bonding

1. Ionic

2. Non-polar covalent

3. Polar covalent

1. Polar bonds are formed between the atoms that do not have a difference in electronegativity.

2. Polar bonds are formed between the atoms that have a significant difference in electronegativity.

3. The nature (polar / non-polar) of a bond does not depend on the electronegativity of the atoms involved in forming the bond.

3. Cannot say

1. Non-polar covalent

2. Polar covalent

3. Ionic

1. Electronegativity increases as we move towards the top right hand corner of the periodic table.

2. Pauling's scale assigns high electronegative values to noble gases.

3. In the Pauling scale, electronegative values range from -0.5 to 4.0.

4. The higher the electronegativity value, the more electronegative the atom is.

1. shared equally between the two atoms

2. pulled towards the atom with the higher electronegativity value

3. pulled towards the atom with the lower electronegativity value

1. polar in nature

2. non-polar in nature

1. Non-polar covalent

2. Polar covalent

3. Ionic
