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:
filter the hot mixture.
Explanation:
Solid is stayed undissolved since the arrangement is gotten super saturated. On the off chance that solid molecule is available recrysallization won't happen in this way we need expel the solid molecule by filtarion in hot condition itself . Subsequently, arrangement become totally homogenous and recrysallization item will shaped by moderate cooling
