What particle is emitted in the following radioactive decay? 2714si→2713al.

A positron particle  

Explanation:

When 2714Si undergoes radioactive decay to form 2713al then it must have undergone a positron emission.When a particle undergoes positron emission, the mass number remains constant while the atomic number decreases by 1. A positron particle has the same mass with an electron, however, unlike an electron it has a positive charge.

Answer two atoms of oxygen;
