Question

how many protons and neutrons are in one atom of silicon-30? 14 protons and 16 neutrons 16 protons and 14 neutrons 14 protons and 14 neutrons 16 protons and 16 neutrons clear all

Explanation:

Step1: Recall silicon's atomic number

Silicon has an atomic number of 14, so protons = 14.

Step2: Calculate neutrons in Si - 30

Mass number (30) = protons + neutrons. So neutrons = 30 - 14 = 16.

Answer:

A. 14 protons and 16 neutrons
