if an atom has 8 protons, 10 neutrons, and 9 electrons, what would its charge be?\na) +1\nb) 0\nc) -1\nd) -2
Answer
Explanation:
Step1: Define charge calculation rule
Atom charge = (Proton count) - (Electron count) Neutrons have no charge, so they are excluded.
Step2: Substitute given values
Substitute 8 protons and 9 electrons: $\text{Charge} = 8 - 9$
Step3: Compute final charge
Calculate the difference: $\text{Charge} = -1$
Answer:
c) -1
