Answer: [tex]^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e[/tex] is the correct equation for beta decay.
Explanation:
When a beta particle, that is, [tex]^{0}_{-1}e[/tex] is emitted in a radioactive decay then it is known as beta decay.
Therefore, beta decay of Polonium-218 is as follows.
[tex]^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e[/tex]
Therefore, we can conclude that [tex]^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e[/tex] is the correct equation for the given beta decay.
