Converting carbon to nitrogen by increasing the number of protons from 6 to 7 and decreasing the number of neutrons from 8 to 7 is an example of what type of decay? beta decay positron emission electron capture alpha decay

The correct answer is beta decay.

Explanation:

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.

Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

Electron capture is defined as the process an electron is drawn in the nucleus where it combines with a proton to form a neutron and a neutrino particle.

Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units.

In the question, it is asked that carbon atom is converting to nitrogen atom. The equation for this follows:

The above conversion is going via beta decay process.

c is the answer because when something is left after something evaporates that shows the chemical change.
