Electron Capture
In an electron capture or electron absorption reaction our electron particle is a reactant and not a product.

Hey, guys, In this new video, we're gonna take a look at electron capture. Now, the word capture we've been talking about this there is decay in a mission versus capture. Decane. A mission means that you're particle will be a product, but capture means that it'll be a reacted. And here we're talking about an electron. I remember an electron is really just a beta particle. So when we say electron capture, we're really saying beta capture. They're both dealing with an electron beta decay. The electron will be a product, but invade a capture or electron capture. It will be an reacted. So here we're gonna say electron capture involves the absorption, often electron, which remember, we saw as this symbol find unstable nucleus and is represented by the following reaction. So let's think of an example we could deal with Francie um, which is the metal most to the left and the lowest down group one A. So that's fr. And here we'll say we're dealing with isotope to 23. So here capture means that this electron is not gonna be a product, but it's gonna be a reacted. So we're gonna have Francie um 2 23. And Francine has an atomic number of 87. We're gonna absorb an electron. What effect is that gonna do? Well, it's gonna be 2. 23 plus zero. Gives me 2. 23 and then 87 minus one is gonna give me 86. So you become Radan. All right? Okay. So that represents the opposite of beta decay. Instead of doing beta decay, remission were doing beta capture, a k A. Electron capture.

now here. We have to say right balance nuclear equations for each of the following elements after undergoing electron capture. So remember Rutherford was the guy who came up with the three major types of nuclear reactions, and they named Element 104 after him. So here, Rutherford has an atomic number of 104 here. We're dealing with isotope to 63. We're gonna absorb an electron. So to 63 plus zero gives me to 63 104 minus one. Give me 103 And that will be L R for the next one. We're dealing with Nobel, Liam. Okay, so Nobel Prize, Nobel, Liam. So here, we're gonna have no belly, um, to 60 which is We absorbing electron. So to 60 plus zero is to 60 one or two minus one is one on one. That's M D. You'll find that a lot of elements around Nobel, you are named after states named after countries named after just inventors and physicists and scientists. So there's a lot of elements that are named after people we might have heard off or may not have heard off. So here we have 2 to 60/1. 01 m D. And finally we have led to 07 so this would be 207 The atomic number of lead is 82. We absorb an electron, so 207 plus zero is 207 80 to minus one is 81. So this would be an example of electron capture, which is the opposite of beta decay or a mission invaded a care admission. The electron is not a reactant but a product.
