The answer would be letter b
The number of neutrons possessed by an isotope beryllium-9 is 5.
<h3>What is neutron?</h3>
Neutron is a subatomic particle forming part of the nucleus of an atom and having no charge.
The number of neutrons in the atom of an element can be calculated by subtracting the number of protons or atomic number from the mass number.
That is; no. of neutrons = mass number - no of protons
According to this question, Beryllium has an atomic number or proton number of 4. The number of neutrons in an isotope of beryllium-9 is as follows:
no of neutrons = 9 - 4 = 5
Therefore, the number of neutrons possessed by an isotope beryllium-9 is 5.

Answer:
Extreme heat will cause the substance molecules to move faster and cause a phase change this phase change would occur if left in an extremely hot area causing the molecules to spread apart.
Explanation:
Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.
