a radioactive nuclide that is used to label blood platelets has 49 protons and 62 neutrons. which is the symbol of this nuclide?\n$_{62}^{49}in$\n$_{49}^{62}in$\n$_{111}^{49}in$\n$_{49}^{111}in$

Answer

Explanation:

Step1: Identify element by proton number

The number of protons determines the element. With 49 protons, the element is Indium (In).

Step2: Calculate mass number

Mass number = number of protons + number of neutrons. So, $49 + 62=111$.

Step3: Write nuclide symbol

In the nuclide symbol ${Z}^{A}X$, $Z$ is the atomic number (number of protons) and $A$ is the mass - number. So the symbol is ${49}^{111}\text{In}$.

Answer:

$_{49}^{111}\text{In}$ (corresponding to the fourth option in the multiple - choice list)
