Answer
Missing atom: $^{14}_6C$
Complete equation:
$^{14}_6C -- \gt ^{14}_7N + ^0_{-1}e$
Work Step by Step
1. Calculate the mass number of the missing atom.
- The sum of the mass numbers on the right side must be equal to that on the left side.
$? = 14 + 0$
$? = 14$
2. Calculate the atomic number of the missing atom.
- The sum of the atomic numbers on the right side must be equal to that on the left side.
$? = 7 - 1$
$? = 6$
3. Identify the symbol of the element with atomic number equal to 6 (Use a periodic table):
- It is "C".
4. Write the symbol with the atomic and mass numbers, and write the complete nuclear equation:
$^{14}_6C$
$^{14}_6C -- \gt ^{14}_7N + ^0_{-1}e$
