Answer:

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.
