a radioactive nuclide is used to detect eye tumors. an atom of this radionuclide contains 15 protons, 15 electrons, and 17 neutrons. which is symbol of this radionuclide?\n$_{17}^{32}p$\n$_{15}^{17}p$\n$_{15}^{30}p$\n$_{15}^{32}p$
Answer
Explanation:
Step1: Identify the element
The number of protons determines the element. Since there are 15 protons, the element is phosphorus (P).
Step2: Calculate the mass - number
The mass - number (A) is the sum of protons and neutrons. Given 15 protons and 17 neutrons, $A=15 + 17=32$.
Step3: Write the nuclide symbol
The nuclide symbol is written as ${Z}^{A}X$, where Z is the atomic number (number of protons) and A is the mass - number. For phosphorus with Z = 15 and A = 32, the symbol is ${15}^{32}P$.
Answer:
$_{15}^{32}P$
