How many particles are in the nucleus of an atom of xenon?
There can be between 124 and 136 particles (neutrons and protons) in the nucleus of a xenon atom.
How do i determine the daughter nucleus formed when a radon-222 nucleus emits a alpha particle?
First, you figure out how many protons and neutrons Radon-222 has. Find the atomic number - that's the number of protons. Subtract that from 222 to get the number of neutrons.From that, you subtract an alpha particle - i.e., 2 protons and 2 neutrons. Use the number of protons to look up the element. Add protons and neutrons to get the isotope number. As an alternative, since you don't really need the number of neutrons, you can just subtract 2 protons, and a total of 4 nucleids from the parent nucleus.
What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
How many protons do Argons have?
Argon atoms have 18 protons which is similar to the number of electrons.
How many protons in the carbon atom?
6 protons 6 neutrons 6 electrons 4 valence electrons
How many neutrons are in the nucleus of an atom of argon-42?
Neutrons = 24 Protons = 18 Electrons = 18
How many protons nuetrons and electrons are in argon?
Argon has 18 electrons and protons...Neutrons is 22
How many protons and neutrons are in the nucleus americum oxide?
There are 214 protons and neutrons in the molecule.
How many protons and neutrons does argon atom have?
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
How many protons nutrons and electrons does argon have?
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%
How many protons and neutron are in argon-38?
18 protons and 20 neutrons
How many protons and neutrons are in the nucleus of the isootope helium-5?
2 protons 3 neutrons
How many neutrons protons and electrons does one nucleus of cobalt have?
27 protons, 32 neutrons, 0 electrons.There are no electrons in the nucleus, they are in the orbitals surrounding the nucleus.
How many protons nuetrons and electrons does argon have?
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.
How many neutrons and electrons in the element argon?
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
How many nutrons does argon have?
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.
How many protons and how many neutrons in the nucleus of a helium 4 atom?
2 protons and 2 neutron
