Molybdenum
Calcium is a metal element. Atomic mass of it is 40.
Hydrogen is a non metal element. Atomic number of it is 1. It is the element with lowest atomic number.
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 (Mo)" is the element with atomic number 42 on the periodic table. It is a silvery-gray metal commonly used in alloys and as a catalyst in various chemical processes.
Calcium is a metal element. atomic number of it is 20.
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.
Indium has atomic number 49.
Ceasium is a metal element. Atomic number of it is 55.
Ceasium is a metal element. Atomic number of it is 55.
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.
Technetium (atomic number 43) is the inner transition metal with the lowest atomic number.
Silver is a metal element. Atomic number of it is 47.
