What kind of radiation is emmitted in the following nuclear reaction

Hello!

There are three main types of radiation decay. These are called alpha, beta, and gamma decays.

Alpha particles are helium atoms with a +2 charge. They have no electrons, two protons, and two neutrons. It's symbol is 4/2He or 4/2α.

Beta particles are like an electron with a -1 charge. It has zero protons and neutrons. These particles have two symbols: 0/-1e or 0/-1β.

Gamma particles are photons, which are made of light energy. It has no mass and has a symbol as 0/0γ or three squiggly lines.  

Looking at the given nuclear reaction, it has 0/-1e in it's equation.

Therefore, the radiation emitted in the nuclear equation is beta, the second choice.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
