Electronegativity Trends

Electronegativity is...

• how good an atom is at attracting electrons

• the ability of an atom to lose electrons

• the energy required to remove an electron from a specific atom

• how easy it is to make friends. 

The element with the largest electronegativity in the halogens is - 

• At

• F

• Cl

• Br

What is the trend of electronegativity in the d-block elements (transition metals)?

• It significantly increases across the period

• It significantly decreases across the period

• It shows little variation across the period

• It first increases, then decreases across the period

Imagine Luna, Kai, and Scarlett are secret agents on a mission in their chemistry class. Their mission, should they choose to accept it, is to identify the most electronegative element in the 4th period of the Periodic Table. This information is crucial for their project related to environmental chemistry. Can you help them identify the element?
