Unit 1 : Electronegativity Flashcards
1
Q
What is the definition of electronegativity
A
The attraction that an atom has for a shared pair of electrons
2
Q
What is the trend going accord a period
A
Increases across a period due to the nuclear charge increasing, and the outer electrons lie closer to the nucleus
3
Q
What is the trend going down a group
A
Decreases down a group due to shielding effect increasing due to extra shells, and the outer shells lie further away from the nucleus each time
4
Q
Why are there no electronegativity values for the noble gases
A
Because they already have a full outer shell
