Marble is a metamorphic rock.
Marble is a metamorphic rock, that forms when limestone (another rock) reaches a certain pressure and heat. It's composed of mostly calcite, and some other minerals like pyrite, quartz, iron oxide, and granite.
Over several years, marble is supposed to wear down from acid rain/weathering.
Explanation:
Isotopes:
₁₅³¹P and ₁₅³²P
Given parameters:
₁₅³¹P ₁₅³²P
Mass number = 31 32
Atomic number = 15 15
The two atoms are isotopes. Now let us derive numbers of their subatomic particles
₁₅³¹P ₁₅³²P
Protons 15 15
Electrons 15 15
Neutrons (31-15) = 16 (32-15) = 17
Because they are isotopes, they differ in the number of neutrons alone.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of their neutrons.
We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.
