Answer:
Third figure shows the best relationship.
(c) is correct option.
Explanation:
Given that,
The diagram best represents the relationship masses of subatomic particles.
We know that,
The mass of proton and neutron are same.
The mass of electron is less than mass of the proton and neutron.
We need to find the best represents the relationship masses of subatomic particles
According to figure,
Third figure shows the best represents the relationship masses of subatomic particles.
Hence, Third figure shows the best relationship.
(c) is correct option.
H₃As is stronger acid than H₂Se.
The H-A bond strength typically determines the size of the "As" atom in an acid; the smaller the "As" atom, the stronger the H-A bond. In the Periodic Table, the atoms get bigger and the bonds get weaker as you advance down a row, strengthening the acids.
<h3>What is acid?</h3>
Any molecule or ion that may donate a proton—a Brnsted-Lowry acid—or establish a covalent bond with a pair of electrons—a Lewis acid—is regarded as an acid. The first class of acids are the Brnsted-Lowry acids, often known as proton donors.
The compound is referred to chemically as lysergic acid diethylamide, or LSD as it is more commonly known. Using it may lead you to have a distorted perception of reality and objects because it has a potent hallucinogenic effect. LSD has an effect known as tripping.
Aqueous solutions of acids with a pH lower than 8 are frequently referred to as "acids," even though the term "acid" technically only refers to the solute.

4f its the last orbital of the above
Answer:
The binding energy released is 1.992 X 10⁻¹⁸ J
Explanation:
Given;
mass of the alpha particle, m = 6.64 x 10⁻²⁷ kg
speed of the alpha particle, c = 3 x 10⁸ m/s
The binding energy released is given by;
where;
m is mass of the particle
c is speed of the particle
E = 6.64 x 10⁻²⁷ (3 x 10⁸)²
E = 1.992 X 10⁻¹⁸ J
Therefore, the binding energy released is 1.992 X 10⁻¹⁸ J
Answer:
A
Explanation:
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, making it useful for the main group elements (elements not in the transition metal or inner-transition metal blocks); an octet in these atoms corresponds to an electron configurations ending with s2p6 .
