The optimal number of neutrons for a nucleus containing 70 protons is 130

<h3>Further explanation </h3>

In chemistry, the nucleus is the positively charged center of the atom that consist of protons and neutrons. It's also known as the "atomic nucleus"

The neutron is a subatomic particle with no net electric charge and a mass slightly greater than that of a proton. The neutron is have symbol n or n⁰. Protons and neutrons constitute the nuclei of atoms.

Neutron is a type of atomic particle which does not possess any kind of charge on it. It has neutral behavior toward atoms since it does not possess any kind of charges but it contributes to the mass of the atoms.

Atomic number = 70

Atomic weight = 173

Atomic weight = number of protons + number of neutrons

Atomic number = number of protons

Therefore, the number of protons = 70

Number of neutrons = atomic weight - number of protons

Number of neutrons = 173 - 70 = 103

Optimal number of neutrons = 130

Atomic number 70

weight 173

number of neutron = weight - Atomic number

= 173 -70

=103

Bubbles in soda rise to the surface. Explain this in terms of density.
algol [13]

Answer:

Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them. This is just like helium in air; helium is lighter than air, so it rises, pushed to the top by the pressure around it.
