17 plus 17 equals 34.
However, Chlorine-34 does not exist; the stable isotopes are Chlorine-35 and Chlorine-37.
Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
The C-12 isotope has 6 protons and 6 neutrons.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
Mass number = No. of protons + No. of neutrons = 19 + 20 = 39
The number of protons and electrons is always the same as the atomic number, which for chlorine is 17. The number of neutrons is always the mass number minus the atomic number, which for this isotope is also 17.
Sodium has 11 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a sodium isotope = Mass number - 11
Chlorine has the atomic number of 17. To keep it neutral then, it must have 17 protons and 17 electrons. Chlorine's most common isotope is 35Cl. That means it has 35 - 17 = 18 neutrons.
The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.
An isotope of an element has a specific number of neutrons. (Calculated as the mass number minus the atomic number) Most elements have more than one isotope, for example Cl with 17 protons has three naturally occurring isotopes in nature, chlorine-35, with 18 neutrons and chlorine 37 with 20 neutrons along with a trace of chlorine-36 with 19 neutrons.
Chlorine atoms always have 17 protons. The number of neutrons equals the mass number of the isotope named minus the number of protons: in this instance, 35 - 17 or 18.
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
The C-12 isotope has 6 protons and 6 neutrons.
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
Chlorine atom has 17 protons and 17 electrons. The number of neutrons depends on the isotope considered. Chlorine has four isotopes: Cl-35, Cl-36, Cl-37 and Cl-38 with 18, 19, 20 and 21 neutrons respectively. However out of these, Cl-35 and Cl-37 are the most stable isotopes.
