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.
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.
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.
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
42
These elements are in the periods 5 to 7.
42 protons, 42 electrons, 14 neutrons(?) Whatever the atomic number is, that's the the number of protons are there.
To find the number of neutrons, subtract the atomic number (number of protons) from the mass number. For this atom with an atomic number of 42 and a mass number of 96, the number of neutrons would be 96 - 42 = 54 neutrons.
The atomic number of an element is defined by the number of protons in its nucleus. In a neutral atom, the number of electrons equals the number of protons, meaning the number of neutral particles (neutrons) can vary. If 42 is your atomic number, you have 42 protons, and the number of neutrons would depend on the specific isotope of the element. For example, if considering molybdenum (atomic number 42), it typically has about 54 neutrons in its most stable isotope.
Molybdenum
The number of arrays (or subsets) that can be formed from a set of 42 elements is determined by the formula (2^n), where (n) is the number of elements in the set. Therefore, for 42 elements, the number of possible arrays is (2^{42}), which equals 4,398,046,511,104. This includes all possible combinations, including the empty set and the full set itself.
