3、One major difference between electron affinity and ionization energy is that when we talked about ionization energy, remember ionization energy always has to be positive.
6、Yeah. OK. We're looking for the lowest ionization energy.
9、The ionization energy, of course, is just the negative of the binding energy.
12、Whenever you hear the term ionization energy, make sure you keep in mind that unless we say otherwise, we're talking about that first ionization energy.
15、The first ionization energy of lithium is about 5.4 electron volts per atom.
18、And the glitch that doesn't make sense just through periodic trends, is that it turns out that the ionization energy of boron is actually less than the ionization energy up beryllium.
21、So, what we can do instead of talking about the ionization energy, z because that's one of our known quantities, so that we can find z effective.
24、Now this is a good place to start, because we are very familiar with ionization energy, we've been talking about it it's that minimum energy required to remove an electron from an atom.
27、So we should be able to calculate a z effective for any atom that we want to talk about, as long as we know what that ionization energy is.
2、So, this is first ionization energy, let's think about second ionization energy.
7、Ionization potential (ionization energy) : Amount of energy required to remove an electron from an isolated atom or molecule.
11、Moreover, we also deduced their correspondent values of lattice relaxation energy and optical ionization energy.
16、Our ionization energy is going to be equal to the incident energy coming in, minus the kinetic energy of the electron.
20、Well, if we look on the chart, the first ionization energy is what is reported in your Periodic Table.
25、So, what we call this is the third ionization energy, or the negative of the binding energy, again of the 2 s orbital, but now it's in boron plus 2 to we're starting with.
1、And we can calculate the ionization energy.
8、We would expect the ionization energy to decrease, that means that sulfur has our lowest ionization energy.
14、So, in terms of ionization energy, we would expect to see sulfur in the middle.
22、If something has a high ionization energy, it means that it really, really, really does not want to give up an electron.
28、So, as we go down a column, we see ionization energy's going to decrease.
10、We know that binding energy is always negative, ionization energy is always positive.
19、Same sort of subtraction problem, what do we have for the ionization energy of the 2 s electron?
4、So, we can now calculate the ionization energy here.
17、Calculation of ionization energy in sulfur,argon and kalium atom by screened hydrogenic model with l-splitting
5、So, oftentimes you'll just be asked about ionization energy.
26、So, if we just rearrange this equation, what we find is that z effective is equal to n squared times the ionization energy, IE all over the Rydberg constant and the square root of this.
13、Relation between ionization energy of isoelectronic atom & ion and atomic number;
23、We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.
