13. complete the summary table for the different types of decay. symbol what it produces change in mass…

Explanation:

Step1: Recall alpha - decay properties

In alpha decay, an alpha particle ($\alpha$) which is a helium - 4 nucleus ($_{2}^{4}He$) is emitted. The number of protons (atomic number) decreases by 2 and the mass number decreases by 4. It produces a daughter nucleus with a lower atomic and mass number.

Step2: Recall beta - decay properties

In beta decay (beta - minus decay), a neutron changes into a proton and an electron (beta particle, $\beta^-$) is emitted. The number of protons increases by 1 and the mass number remains the same. It produces a daughter nucleus with a higher atomic number but the same mass number.

Step3: Recall gamma - decay properties

In gamma decay, a high - energy photon ($\gamma$) is emitted. There is no change in the number of protons or the mass number. It produces a more stable nucleus in a lower energy state.

Decay Type	Change in Atomic Number (Protons)	Change in Mass Number	What it Produces	Symbol
Alpha Decay	- 2	- 4	A daughter nucleus with lower atomic and mass numbers	$_{2}^{4}He$ or $\alpha$
Beta Decay	+ 1	0	A daughter nucleus with a higher atomic number and the same mass number	$_{ - 1}^{0}e$ or $\beta^-$
Gamma Decay	0	0	A more stable nucleus in a lower energy state	$\gamma$

Answer:

Decay Type	Change in Atomic Number (Protons)	Change in Mass Number	What it Produces	Symbol
Alpha Decay	- 2	- 4	A daughter nucleus with lower atomic and mass numbers	$_{2}^{4}He$ or $\alpha$
Beta Decay	+ 1	0	A daughter nucleus with a higher atomic number and the same mass number	$_{ - 1}^{0}e$ or $\beta^-$
Gamma Decay	0	0	A more stable nucleus in a lower energy state	$\gamma$
