Okay, so when we talk about the lattice energy, lattice energy is based on kulom's law or kulombic attraction, and that's going to be based on the magnitude of charge versus the ion size.
00:20
It's going to be the force is equal to a constant times the charges, q1 times q2, over the radius squared.
00:31
So the small radius squared.
00:34
In the denominator.
00:37
The charges plus two minus two has a bigger effect than, you know, plus one, minus one because two times two is four.
00:46
That is going to make a larger magnitude in the top here.
00:50
So the larger the magnitude of charge, the smaller the size of the ions, the closer the ion centers can get to each other, the higher the magnitude of lattice energy.
01:01
The more exothermic it will be, when the ions come together from the gas phase.
01:08
So i actually look them up to explain this trend where n -a is smaller than k, but they have equal ion sizes, and f is smaller than cl...
