Argon is a noble gas that has the chemical symbol of Ar. It can be found in the atmosphere and also in many household products like air conditioners, refrigerators, and even your car’s air filter! Argon doesn’t have any electrons to share with other atoms or molecules. So does argon have 2 valence electrons? No, it doesn’t! How about 1 valence electron? Nope! How can you find out if it’s full or not then? There are actually a few different ways to do this if you don’t want to count yourself:
If the atomic number is 18 (the same as nitrogen), then there must be 10 more protons than electrons.
If it has an electronegativity that is less than or equal to 0.35, then it has a full valence shell.
If the atomic number plus the proton number equals 18 and it’s electronegative value is greater than zero, then there must be more protons than electrons.
So does argon have any valence electrons? Yes! Argon has two valance electrons which are found in its outermost energy level called the orbital quantum shells of an atom. This means that all four orbitals are filled with two atoms each. These orbitals can hold up to eight electron particles at a time but only six take part in bonding so this leaves room for one lonely little electron on your outside edge making you prone to reactivity as well as being a conductor of electricity.
The valence shell of argon is full. How can you find the valency of argon?
To figure out how many electrons are in a given orbital, divide the number by two. If your atomic radius plus proton number equals 18 and its electronegative value is greater than zero, then there must be more protons than electrons and all four orbitals will hold up to eight electron particles at a time but only six take part in bonding so this leaves room for one lonely little electron on your outside edge making you prone to reactivity as well as being a conductor of electricity! These six outermost energy levels are called quantum shells which means that they have an infinite amount of potential spatial arrangements with different energies.
In the valence shell, there is a maximum of four electrons. This means that argon has two valence electrons and will never be an atom with full valence in its outermost energy levels. It is possible for argon to have other shells which are not empty but if it does, then they must only contain up to two electrons as this makes up the maximum limit of all orbitals together per proton number divided by half!
Those who want to know how many protons or neutrons an element has, should remember that these particles can’t change their spin and so they always keep one unit on either side at any given moment. The total number of protons plus neutrons (or vice versa) is called the mass number.
In order for an element to have more than two valence electrons, it would need more protons in its nucleus and so would be a transition metal or an alkali earth metal. Such metals can also comprise other orbitals which are not empty but if they do contain up to four electrons then they must only reside on one of these specific levels!
If there were no such restrictions, each electron could start occupying new orbits at any time – this is how the early universe was like before atoms began forming due to nuclear binding energy (or Coulomb force).
The argon atom has 18 neutrons and 18 protons meaning that it will never form full outer shells because even with all of the electron orbitals filled, it would only have 18 electrons.
Argon is a noble gas and so does not need to engage in chemical bonding (or oxidation) because they are never reactive. Noble gases do however still react but these reactions involve ions – this includes argon! Argon reacts with other elements such as chlorine which forms an ionic compound called ArCl+ that has a high boiling point of 269°C or 1657°F.”
