SSC MTS EXAM

Detailed explanation-1: -In beta minus ( −) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. + decay is also known as positron emission.

Detailed explanation-2: -During beta-minus decay, a neutron in an atom’s nucleus turns into a proton, an electron and an antineutrino. The electron and antineutrino fly away from the nucleus, which now has one more proton than it started with. Since an atom gains a proton during beta-minus decay, it changes from one element to another.

Detailed explanation-3: -Beta decay is a radioactive decay in which a beta ray is emitted from an atomic nucleus. During beta decay, the proton in the nucleus is transformed into a neutron and vice versa. If a proton is converted to a neutron, it is known as + decay. Similarly, if a neutron is converted to a proton, it is known as – decay.
