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

1

_______ is a measure of the ability of a chemically combined atom to attract electrons to itself.
*____is the highest Electronegativity.
*Electronegativity is the opposite of _______
* largest radii is at ________

Electronegativity
4.0
Atomic radium

2

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
