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?\no $_{17}^{32}p$\no $_{15}^{17}p$\no $_{15}^{30}p$\no $_{15}^{32}p$
Answer
Explanation:
Step1: Identify the element
The number of protons determines the element. Since there are 15 protons, the element is phosphorus (P) as the atomic number of an element is equal to the number of protons, and phosphorus has an atomic number of 15.
Step2: Calculate the mass - number
The mass - number (A) of an atom is the sum of the number of protons (Z) and neutrons (N). Given Z = 15 and N = 17, then A=Z + N=15 + 17=32.
Step3: Write the nuclide symbol
The nuclide symbol is written as $Z^A\text{X}$, where X is the chemical symbol of the element, A is the mass - number, and Z is the atomic number. For phosphorus with A = 32 and Z = 15, the symbol is ${15}^{32}\text{P}$.
Answer:
$_{15}^{32}\text{P}$
