Electronegativity and Chemical Bonding

The video tutorial explains why nitrogen is more electronegative than carbon. It highlights that both elements have the same number of energy levels, but nitrogen has an additional proton, increasing its atomic number. This extra proton gives nitrogen a stronger positive charge, allowing it to attract electrons more effectively in chemical bonds. The video also discusses periodic table trends, showing that electronegativity increases across periods, with nitrogen having a higher value than carbon. The tutorial concludes by reinforcing the concept that nitrogen's extra proton enhances its electronegativity.

Which element is more electronegative, carbon or nitrogen?

• Carbon

• Both are equally electronegative

• Nitrogen

• Neither

What is the main reason nitrogen is more electronegative than carbon?

• It has an extra proton

• It is lighter

• It is a gas

• It has more electrons

How does nitrogen's extra proton affect its chemical bonding?

• It has no effect

• It makes nitrogen unstable

• It attracts electrons from less electronegative elements

• It repels other atoms

What happens to electronegativity as you move across a period in the periodic table?

• It remains constant

• It increases

• It fluctuates

• It decreases

What are the electronegativity values for carbon and nitrogen, respectively?

• 3.04 and 2.55

• 2.00 and 3.00

• 2.55 and 3.04

• 3.00 and 2.00
