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.
Answer:
The correct answer is: It loses electrons.
Explanation:
In the reactions of oxide reduction (redox), one substance gives up electrons and the other accepts them. Involved: reducing agent (yields electrons, increases its oxidation number: oxidizes) and an oxidizing agent (accepts electrons, decreases its oxidation number: reduces).
At the half equivalence point [HA] = [A-] and pH = pKa
<span>if Ka is 5.2e-5 then pKa = pH = 4.28</span>
In ions atoms lose and gain electrons
