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.
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.
An atom that has more neutrons than protons is called an Isotope.
mass number = protons + nuetrons
A Chlorine atom typically has 18 neutrons in its nucleus. This is because the atomic number of Chlorine is 17, which represents the number of protons in its nucleus. By adding the number of protons to the number of neutrons, we can determine the total number of particles in the nucleus.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
Yes, the main isotope of chlorine has 17 protons and 18 neutrons.
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.
No, an atom of chlorine with 20 protons would not be chlorine-37. Chlorine-37 has 17 protons and 20 neutrons, totaling 37 particles in its nucleus. The number of electrons in a neutral chlorine-37 atom would be 17, not 20.
Outside the nucleus (where the protons and neutrons are) in a "cloud".
Within an atom the protons and neutrons are located at the center of the atom, the location is called the nucleus.
Mass number = No. of protons + No. of neutrons = 19 + 20 = 39
17 electrons. The number of protons and electrons is always the same.
Chlorine has an Atom number of 17 and atom mass of 35.45. So atom mass - atom number gives you 18.45
An assembly of protons and neutrons within an atom is called a nucleus. It is the central part of an atom that contains most of the mass of the atom and is positively charged due to the protons it contains.
An atom with 17 protons and 20 neutrons would be chlorine-37, which has a total atomic mass of 37 (17 protons + 20 neutrons).
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
An atom that has more neutrons than protons is called an Isotope.
