To understand this question, we need some knowledge on radioactive decay. This type of nuclear decay is called a beta decay
<h3>Beta Decay</h3>
This is the process where a radioactive material is fired or naturally emits a beta particle which is equivalent to the lose of an electron and spontaneously becomes an entirely different element.

The participating actors in this nuclear reaction are
This is the decay process of helium particle in which it became a lithium particle and emitted an electron in the process.

Step-by-step explanation:
Answer:
II. The value of square root of 6 is between 2.43 and 2.45, whereas the value of square root of 7 is between 2.63 and 2.65.
Step-by-step explanation:
A square root is an operation which asks what times itself will give theis number. Some numbers will have whole number square roots but many do not. The numbers which do are called perfect squares like 1, 4, 9, 16, 25, 36, etc.... You can approximate other square roots by comparing them to the nearest perfect square.
The √6 and √7 is between the √4 and the √9 since these are the nearest perfect squares. The √4 = 2 and √9 = 3. This means the √6 and √7 is between 2 and 3. Statement I is not true since these values are too large. Statement II is true.
