Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface

The mass number of an oxygen atom with 8 protons and 8 neutrons is 16. The mass number of an atom is the total number of protons and neutrons in the nucleus. This atom is an isotope of oxygen, called oxygen-16.
The mass number of an oxygen atom that has 8 protons and 8 neutrons in the nucleus is 16.
The mass number of an atom is the total number of protons and neutrons in its nucleus. The number of protons in an atom is also the atomic number, which identifies the element. In the case of oxygen, the atomic number is 8, because there are 8 protons in the nucleus.
Neutrons are subatomic particles that, together with protons, make up the majority of an atom's mass. Neutrons and protons have approximately the same mass, while electrons are much lighter. Therefore, the mass number, which represents the sum of the number of protons and neutrons, provides a good estimate of the mass of an atom.
In this case, the atom is an isotope of oxygen, known as oxygen-16, because it has 8 protons and 8 neutrons. Isotopes are atoms of the same element that have different numbers of neutrons and therefore different mass numbers. Oxygen-16 is the most abundant isotope of oxygen, making up about 99.76% of all oxygen atoms.
