The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
The atomic number of arsenic is 33, which means it has 33 protons in its nucleus.
The element with atomic mass 74.922 is Selenium, with atomic number 34. It is a nonmetal with various applications in industry and technology, particularly in solar cells and glass production.
The element with an average atomic mass of 190.2 is Tungsten (atomic number 74).
To find the number of neutrons in an atom, you subtract the atomic number from the mass number. In this case, the number of neutrons would be 33 (58 - 25 = 33).
The atomic number for an element is the number of protons in its nucleus, which is 33 for arsenic (As). The mass number is the sum of protons and neutrons in the nucleus, so for arsenic-33 (As-33) specifically, the mass number would be 33.
