Answer: [tex]_{-1}^0\beta[/tex]

Explanation:  

General representation of an element is given as:   [tex]_Z^A\textrm{X}[/tex]

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Beta decay : In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

[tex]_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta[/tex]

The given reaction would be represented as:

[tex]_{43}^{98}\textrm{Tc}\rightarrow_{44}^{98}\textrm{Pb}+_{-1}^0\beta[/tex]

Answer: Option (a) is the correct answer.

Explanation:

The high energy electrons are known as beta particles. Charge on a beta particle is -1, that is, similar to the charge present in an electron.

Hence, symbol that represents a beta particle is [tex]^{0}_{-1}\beta[/tex].

For example, [tex]^{98}_{43}Tc \rightarrow ^{98}_{44}Ru + ^{0}_{-1}\beta[/tex]

This reaction is a radioactive decay rection when [tex]^{98}_{43}Tc[/tex] on decaying gives [tex]^{98}_{44}Ru[/tex]along with emission of a beta particle.

Whereas [tex]^{4}_{2}He[/tex] is an alpha particle,  [tex]^{0}_{0}\gamma[/tex] is a gamma particle, and [tex]^{1}_{0}n[/tex] is a neutron.

Thus, we can conclude that the particle [tex]^{0}_{-1}\beta[/tex] would complete this given beta decay reaction.
