A Periodic Table should be useful here, there even is a link provided for you below. One glance at the forty second element on the table should give you your answer.
the element is molybdenum.
To make it short and sweet, lets keep it simple. There is one element that has the atomic number of 42, and it is Molybdenum.
Molybdenum (Mo)
That is Molybdenum (Mo).
An element's atomic number gives its number of protons. Checking the periodic table, we see that molybdenum is the element with the atomic number of 42. Thus molybdenum has 42 protons in its nucleus.
The atomic number is the number of protons in an element. Ex: Molybdenum's A.N. is 42. so it has 42 protons.
No. of neutrons= Mass no.- No.of protons(atomic no) therefore, no. of neutrons =96-42 = 54
Calcium has atomic number 20, which means that all calcium atoms have 20 protons in their atomic nuclei. Neutral calcium atoms also have 20 electrons. Isotopes of calcium vary in the number of neutrons in their atomic nuclei, and are named for their mass number, which is the sum of the protons and neutrons in the nucleus. You can calculate the number of neutrons (N) in an isotope by subtracting the number of protons (atomic number) from the mass number. N = 42 - 20 = 22, therefore, a calcium-42 isotope has 20 protons, 20 electrons, and 22 neutrons.
molybdenum has 13 protons and 13 electrons

The atomic number 33 is for arsenic (As); the nucleus contain 33 protons and 42 neutrons.
If 42 is the atomic number then there is 42 electrons in isotope.
Molybdenum-96 (not Mo-96) or Mo 96 42 has 42 protons and 54 neutrons. The atomic number is number of protons The mass number minus the atomic number is number of neutrons
These elements are in the periods 5 to 7.
An element's atomic number gives its number of protons. Checking the periodic table, we see that molybdenum is the element with the atomic number of 42. Thus molybdenum has 42 protons in its nucleus.
42
42 protons, 42 electrons, 14 neutrons(?) Whatever the atomic number is, that's the the number of protons are there.
Molybdenum's atomic number is 42 and its atomic weight is 95.94
Molybdenum
The atomic number is the number of protons in an element. Ex: Molybdenum's A.N. is 42. so it has 42 protons.
