An element has an atomic mass number of 16 and an atomic number of 7. how many protons and neutrons do they have

Explanation:

Total number of protons present in an atom or element is known as the atomic number. On the other hand, sum of total number of protons and neutrons present in an element is known as a

For example, an atom with atomic number 7 and atomic mass 16 means there are 7 protons.

Whereas number of neutrons are calculated as follows.

             Atomic mass = no. of protons + no. of neutrons

                    16 = 7 + no. of neutrons

                    no. of neutrons = 16 -7

                                               = 9

Thus, we can conclude that the given atom contains 7 protons and 9 neutrons.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
