Question

how many protons, neutrons, and electrons are there in a neutral atom of ( ^{30}\text{p} ) (phosphorus-30)? protons: electrons: neutrons:

Explanation:

Step1: Find atomic number of P

Phosphorus (P) has atomic number 15, so protons = 15.

Step2: Determine electrons in neutral atom

In neutral atom, electrons = protons = 15.

Step3: Calculate neutrons

Mass number (30) = protons + neutrons. So neutrons = 30 - 15 = 15.

Answer:

protons: 15
electrons: 15
neutrons: 15
