If Bromine has an atomic number of 35 and has 45 neutrons what is its mass number?
The mass number of an element is the sum of its protons and neutrons. Since Bromine has 35 protons (atomic number) and 45 neutrons, its mass number would be 35 + 45 = 80.
What is the element argon atomic number?

What does the atomic number equal of an element?
The atomic number of an element equals the number of protons in the element.
What number of protons in one atom of an element is that element's?
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
If an element has an atomic number of 45 and an atomic mass of 92 the number of protons it has is?
The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
