Answer:
2. Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
3. Since the vast majority of an atom's mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).

Answer : The density of the block is estimated to be, 
.
Explanation :
Density of the water, 
As we know that,
Buoyant force = 
where,
g = gravitational acceleration
volume of the block = v
density of the block = 
Weight of the Block = Buoyant force exerted by water
Thus, the density of the block is estimated to be, .
