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
_______ 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 ________
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?
The amount of amount of energy involved in the addition of one electron to a gaseous atom of the elemen
Electron affinity: the amount of ____ involved in the ___ of one electron to a ________ of the element
What is ionizing energy?
Ionizing energy is the energy required to remove an electron from an atom
