What is Electronegativity?
Electronegativity is a measure of the ability of a chemically combined atom to attract electrons to itself.
- 4.0 is the highest Electronegativity.
- Electronegativity is the opposite of atomic radium
- largest radii is at the bottom
What is super conductivity?
Super conductivity is when electrons move with no resistance as temperature drops close to absolute zero.
- Meissner effect : levitating magnets
- 1986 - materiel engineer working with Yittrium Copper Oxides
- wrote Meissners (arrow up) temperature - now super conductivity at 138k
N2(L) = 77 k
What is electron affinity?
