Given that oxygen has an atomic number of eight determine how many protons and neutrons are in the isotope 16o or oxygen -16 8 protons and 9 neutrons 8 protons and 8 neutrons 8 protons and 7 neutrons 16 protons and 0 neutrons

Option (b) is the correct answer.

Explanation:

Atomic number is the sum of only total number of protons present in an element. Whereas mass number or atomic mass is the sum of total number of both protons and neutrons present in an element.

For example, given atom has atomic number is 8.  And, it is known that atomic mass of O is 16 g/mol.

Therefore, number of neutrons present in it will be calculated as follows.

                    Mass number = no. of protons + no. of neutrons

                         16 = 8 + no. of neutrons

                    no. of neutrons = 16 - 8  

                                               = 8

Hence, we can conclude that in the given isotope of oxygen-16 there are 8 protons and 8 neutrons.

the product of the pressure and volume is also constant
