Question

question 4 of 24
write the nuclear symbol for the neutral atom shown.
nuclear symbol:
image shows nucleus with 12 protons, 12 neutrons, 12 electrons

Explanation:

Step1: Determine the atomic number (Z)

The atomic number (Z) is equal to the number of protons. From the diagram, there are 12 protons, so \( Z = 12 \). The element with atomic number 12 is magnesium (Mg).

Step2: Calculate the mass number (A)

The mass number (A) is the sum of protons and neutrons. There are 12 protons and 12 neutrons, so \( A = 12 + 12 = 24 \).

Step3: Write the nuclear symbol

The nuclear symbol is written as \( \ce{_{Z}^{A}X} \), where X is the element symbol. Substituting the values, we get \( \ce{_{12}^{24}Mg} \).

Answer:

\( \ce{_{12}^{24}Mg} \)
