Answer:
-3
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Protons have a positive (+) charge
- Neutrons have a neutral (0) charge
- Electrons have a negative (-) charge
Explanation:
<u>Step 1: Define</u>
7 protons, 9 neutrons, 10 electrons.
+7, +0, -10
<u>Step 2: FInd charge</u>
7 + 0 - 10 = -3
Answer: Option (c) is the correct answer.
Explanation:
A particle that contains two protons and two neutrons bounded together is known as an alpha particle.
It is known that an alpha particle has a large mass and due to this they travel very slowly. As a result, they tend to have low velocity.
Hence, we can conclude that alpha particles cannot penetrate deeply into solids because they have low velocity.
i think its a right tringle
