Explanation and Answer:
This is an opinion based question and there could be many different responses these are just examples of solution to restore the fishery:
-limiting the season during which lobsters can be caught this allows the population to reproduce itself gradually but maintaining it in control
-limiting the amount of lobster that can be caught therefore again letting the population increase
The atomic radii of the atoms in the group 1 increases down the group as we go from Hydrogen to Francium.
<h3>What is atomic radii ?</h3>
The total distance from the nucleus of an atom to the outermost orbital of its electron is known as its atomic radii or atomic radius.
As we go down the group, the number of orbits or shell increases.
Hence, atomic radii of the atoms in the group 1 increases down the group as we go from Hydrogen to Francium.

Answer: A. Decomposition.
Explanation: This is a reaction when a compound breaks down to form two and/or more easier substances. When this reaction turns into a single replacement, only one element is placed there for basically filling in for another element that is in a compound that is similar to the one before. That being said about the substances, this reaction is a big part because it takes away substances, then replaces them with newer and similar ones each time it has completed it's work. It's just a long train of work for Decomposition.
I hope this helps you!
Answer:
The right choice is:
B. 21, 21, 53.
Explanation:
Atomic Number = Number of electrons = Number of protons
So, the No. of protons (A) = Number of electrons =21
Atomic Number (B) = Number of electrons =21
Mass number (C) = Number of electrons + Number of neutrons = 21 + 32 = 53
<u> </u><u>So, the right choice is: </u>
B. 21, 21, 53.
