# what is lepton number sir plzzz tell lepton number of carbon 14?????

In high energy physics, the lepton number is the number of leptons minus the number of antileptons.

In equation form,

$L = n_{\ell} - n_{\overline{\ell}}$

so all leptons have assigned a value of +1, antileptons −1, and non-leptonic particles 0. Lepton number (sometimes also called lepton charge) is an additive quantum number, which means that its sum is preserved in interactions (as opposed to multiplicative quantum numbers such as parity, where the product is preserved instead).

I have tried many websites buti'm not able to find lepton number of an elemnt like C-14

Lepton number has applications in balancing the equation i.e., conservation of some laws during beta-decays etc.

You can have an idea abt it at following link :

hope it helps..!!
