18 protons and 18, 20 or 22 neutrons.
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
The nuclear stability graph shows that there is an optimal ratio of protons to neutrons in an atomic nucleus for stability. Nuclei with too few or too many neutrons compared to protons are less stable.
There are 18, 20 or 22 neutrons.
Argon atoms have 18 protons which is similar to the number of electrons.
The strong nuclear force doesn't balance the electrostatic force.
Neutrons = 24 Protons = 18 Electrons = 18
Argon has 18 electrons and protons...Neutrons is 22
18 protons and 20 neutrons
Argon-39 has 18 protons, 21 neutrons, and 18 electrons.
There are 214 protons and neutrons in the molecule.
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
In order to answer this question, the specific isotope of argon must be known. However, I will answer it using argon-40 because it makes up over 99% of the atoms of argon. Argon-40 has a mass number of 40, meaning that the sum of protons and neutrons in the nuclei of its atoms is 40. In order to use this information to determine the numbers of protons and neutrons, you also need to know the atomic number, which is the number of protons in the nucleus of its atoms. Argon's atomic number is 18, so we know that all argon atoms have 18 protons. To calculate the number of neutrons, we subtract the atomic number from the mass number, which is (40-18)=22 neutrons. The number of electrons equals the number of protons in a neutral atom, so argon atoms have 18 electrons. So, to sum things up, neutral atoms of argon-40 contain 18 protons, 22 neutrons, and 18 electrons.
18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
2 protons 3 neutrons
There are 3 Isotopes with the following mass numbers: Argon 36 Argon 38 Argon 40 Argon has an atomic number of 18 (it therefore has 18 protons in its nucleus and 18 electrons flying round it). To get the number of neutrons one subtracts the atomic number from the mass number. This means that some Argon atoms have 18 neutrons, some 20 neutrons and some 22 neutrons the isotope with 22 neutrons is the most common and forms 99.6% of all Argon.
27 protons, 32 neutrons, 0 electrons.There are no electrons in the nucleus, they are in the orbitals surrounding the nucleus.
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
