The type of reaction is beta decay.
Explicación
## Step 1The given equation represents a type of nuclear reaction where a potassium isotope (with atomic number 19 and mass number 42) decays into a calcium isotope (with atomic number 20 and mass number 42), emitting an electron (also known as a beta particle) in the process. ## Step 2This type of reaction is known as beta decay. In beta decay, a neutron in the nucleus of an atom is converted into a proton, an electron, and an antineutrino. The electron is then emitted from the nucleus.## Step 3The atomic number of the atom increases by one, while the mass number remains the same. This is characteristic of beta decay.
