The atomic number of Chlorine is 17.
The element is chlorine and the isotope is 17Cl35
The isotopic notation for chlorine-35 is ( ^{35}_{17}Cl), representing the atomic mass (35) and atomic number (17) of chlorine.
The atomic number of bromine is 35, while the atomic number of chlorine is 17. This means that bromine has 35 protons in its nucleus, while chlorine has 17 protons. The atomic number determines the element's identity in the periodic table.
In an atom of chlorine with an atomic number of 17, the number of protons in the nucleus is 17. Since the atom is neutral, it will also have 17 electrons. Neutrons can be calculated by subtracting the atomic number from the atomic mass, so for chlorine with an atomic mass of 35, it would have 35 - 17 = 18 neutrons in the nucleus.
Atomic number is unique to an element. Since both Chlorine-35 and Chlorine-37 has atomic number of 17, they are both Chlorine. However they have different atomic mass (caused by different number of neutrons in the atom) thus they are called isotope.
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
the atomic number would be 17 && the mass would be 35
The main difference between chlorine-35 and chlorine-37 is their atomic mass. Chlorine-35 has an atomic mass of 35 amu, while chlorine-37 has an atomic mass of 37 amu. This is due to the different number of neutrons in their nuclei: chlorine-35 has 18 neutrons, while chlorine-37 has 20 neutrons.
Chlorine 35 and chlorine 37 have a different number of neutrons. Chlorine 35 has 18 neutrons, while chlorine 37 has 20 neutrons. This causes them to have different atomic masses.
Fluorine = 9 Chlorine = 17 Bromine = 35 Iodine = 53 Astatine = 85
The mass number is the sum of the protons and neutrons, in this case 35. The atomic number is the same as he number of protons, in this case 17.
Chlorine has a mass number of 35.5 because it is a mixture of two stable isotopes, chlorine-35 and chlorine-37. The average atomic mass of chlorine is calculated by taking into account the abundance of each isotope in nature. The weighted average of these isotopes gives the atomic mass value of 35.5 for chlorine.
