a radioactive nuclide that is used to label blood platelets has 49 protons and 62 neutrons. which is the symbol of this nuclide?\n<sup>49</sup><sub>62</sub>in\n<sup>62</sup><sub>49</sub>in\n<sup>49</sup><sub>111</sub>in\n<sup>111</sup><sub>49</sub>in
Answer
Explanation:
Step1: Determine the atomic number
The atomic number (Z) is equal to the number of protons. Given 49 protons, so Z = 49.
Step2: Determine the mass number
The mass number (A) is the sum of protons and neutrons. A=49 + 62=111.
Step3: Write the nuclide symbol
The nuclide symbol is written as $^{A}{Z}X$, where X is the chemical - symbol. The element with atomic number 49 is Indium (In). So the symbol is $^{111}{49}In$.
Answer:
$^{111}_{49}In$ (corresponding to the last option in the multiple - choice list)
