The mass number of an isotope refers to the number of protons and neutrons it contains in its nucleus. Each variation of an element's atoms will have a different mass number depending on the different numbers of neutrons. The number of protons cannot change without the atom becoming a differe...
Isotopes are atoms of the same element that have a different number of neutrons. They can be identified because they will also have a different mass number, or the mass of one atom of the element. Answer and Explanation:1 The mass number for carbon is 12amu. The mass number is the sum...

In comparison, cars and planes have a greater carbon footprint than other forms of mass transit, such as rail or bus. Cars and light trucks accounted for16% of US greenhouse gases in 2022, according to a University of Michigan factsheet. Trains and buses also contribute to emissions, but ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
While paleontologists have studied fossils for centuries, the science of mass extinction is relatively new. Radiometric dating, based on the natural radioactive decay of certain elements, like carbon, and other techniques revolutionized the ability to precisely determine the age of ancient rocks in the...
