Arsenic (As) has 33 protons, giving it an atomic number of 33 and, in it's most common isotope, it has 42 neutrons. Atomic Mass is equal to (number of protons + number of neutrons). 33 + 42 = 75.

What is the atomic number of rhenium?
Rhenium, with the chemical symbol Re, is the chemical element with the atomic number 75.
Atomic number 50 and mass number 125 contains?
The element with atomic number 50 is tin (Sn). The mass number of 125 indicates that this particular isotope of tin contains 75 neutrons (mass number - atomic number).
How many protons are in rhodium?
Rhenium has 75 protons, 75 electrons and 111 neutrons.The number of protons is equal to the number of electrons.Neutrons can be calculated by subtracting the number of protons from the atomic weight.In this case atomic number is 186 ==> the nr of neutrons = 186-75=111.
What is the mass number of AS?
Asenic is a non metal element. Atomic mass of it is 75.
How many protons electrons and neutrons does an atom with an atomic number of 50 and mass number of 125?
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
What is the atomic number of rhenium?
Rhenium, with the chemical symbol Re, is the chemical element with the atomic number 75.
How do you find the number of proton and atomic number in the mass number 75?
You have to know the element with the mass number of 75. Then you would look it up on the periodic table to find the atomic number, which is the number of protons.
The atomic number of Re is 75 The atomic mass of one of its isotopes is 186 How many neutrons are in an atom of this isotope?
The atomic mass minus the atomic number equals the number of neutrons. Thus in the case above the number of neutrons would calculate out to be 11. HOWEVER PLEASE NOTE Rhenium (Re) does not have an atomic mass of 86, it has two isotopes one of atomic mass 185 and another of atomic mass 187. Thus the real number of neutrons is 110 or 112.
How many protons electrons and neutrons does an atom with atomic number 50 and mass 125 contain?
Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
Atomic number 50 and mass number 125 contains?

In period 6 what element has 75 protons?
The element with 75 protons in period 6 is Rhenium (Re), which has an atomic number of 75.
Which element has an atomic number 6 times greater than that of Beryllium?
Chromium (Cr), which has an atmoic number of 24. Beryllium has an atomic number of 4, so 4*6=24, which is Chromium.
