What is the atomic number and atomic mass number of chlorine?
The atomic number of chlorine is 17, which indicates the number of protons in its nucleus. The atomic mass number of chlorine is about 35.5, which represents the average mass of its isotopes considering their relative abundances.
What is the name of the element with an atomic mass of 197?
The element with an atomic mass of 197 is Gold.
Do you need atomic number to find atomic mass?
No, you do not need the atomic number to find the atomic mass of an element. The atomic mass is the weighted average of the masses of the isotopes of an element, whereas the atomic number is the number of protons in the nucleus.
What element has a 27 atomic mass?
The element with an atomic mass of 27 is cobalt (Co). Cobalt is a transition metal found in the periodic table with atomic number 27.
Is the atomic weight of chlorine 35.5 because of electrons?
No, the atomic weight of chlorine (35.5) is determined by the combined average weight of its protons, neutrons, and electrons. The fractional atomic weight is due to the existence of isotopes of chlorine, with chlorine-35 being more abundant than chlorine-37.
