What is ''GAMMA DECAY''??¿¿​

Answer 1

Answer:

Heya!baby

your answer

Explanation:

In gamma decay, depicted in Fig. 3-6, a nucleus changes from a higher energy state to a lower energy state through the emission of electromagnetic radiation (photons). ... In the gamma decay of a nucleus, the emitted photon and recoiling nucleus each have a well-defined energy after the decay.

hope it helps uh. flw mw...☺❤

Answer 2

Gamma Decay

• γ  ray emission also called Gamma decay.

• In this, the excited nucleus releases a high-energy photon called  γ  rays.

• The daughter nucleus is an isotope.

• Unlike the other modes of radioactive decay, the number of protons and neutrons in the nucleus of the atom are not changed.

• The energy level of the atom is lowered by one to a stable state.

Example

Gamma decay of Technetium-99m into Technetium-99, where 'm' stands for metastable, which in terms of an atom, ion or atomic nucleus, means that the atom is in an excited state:

$\sf _{43}^{99}m \:Tc \longrightarrow _{43}^{99}m \:Tc+\gamma$

α  particle decay

• In this, one Helium nucleus is ejected from the unstable radioactive nucleus.

• The daughter nucleus has mass number of 4 less and atomic number 2 less.  

β  particle decay

• In this, either one electron  β −  is ejected.

• The daughter nucleus has same mass number and atomic number 1 more, or one positron  β +  is ejected.

• In this case the daughter nucleus has same mass number and atomic number 1 less.
