Question

if silicon has an atomic number 14 and mass 28, how many neutrons does it have?

Explanation:

Step1: Recall the formula for calculating neutrons

The formula is \( \text{Number of neutrons}=\text{Mass number}-\text{Atomic number} \).

Step2: Substitute the given values

Given that the atomic number of silicon is \( 14 \) and the mass number is \( 28 \). Substitute these values into the formula: \( 28 - 14 \).

Step3: Calculate the result

\( 28-14 = 14 \).

Answer:

\( 14 \)
