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?
o silicon - 14
o silicon - 32
o silicon - 46
o silicon - 153

Explanation:

Step1: Calculate mass number

Mass number = number of protons + number of neutrons. Given protons = 14, neutrons = 18. So mass number \(A=14 + 18\).

Step2: Evaluate the sum

\(A=32\)

Answer:

silicon - 32
