Question

if we have a sample of silicon (si) atoms that has 14 protons, 14 electrons, and 18 neutrons what is the name of this specific silicon isotope? silicon-14 silicon-32 silicon-46 silicon-153

Explanation:

Step1: Calculate mass number

The mass number of an isotope is the sum of protons and neutrons.
$\text{Mass number} = 14 + 18 = 32$

Step2: Identify isotope name

Isotopes are named by element + mass number.

Answer:

silicon-32
