Why the chlorine not react with the argon?
Argon has three full shells of electrons. Elements react to form bonds so that their outer shell is full. As Argon has a full outer shell it is unreactive
Argon is a stable gas with a very high ionization energy Which statement explains why?
It has a full outer shell of electrons
What will Chlorine loose or gain when it forms an Ion?
Chlorine will gain one electron in order to establish a full outer shell of electrons. Chlorine atoms have 7 valence electrons, but with one extra electron, it can establish a stable octet.
Why are Sodium and Chlorine not stable elements?
Sodium and Chlorine are chemically unstable due to the amount of electrons each has in the outer shells (also known as layers) of their atoms. Sodium has 11 electrons. First shell: 2 electrons Second shell: 8 electrons Third shell: 1 electron As the number of electrons in the last shell is not 8 and as the shell is not full Sodium is chemically unstable. Chlorine has 17 electrons. They are arranged like this: First shell: 2 electrons Second shell: 8 electrons Third shell: 7 electrons The number of electrons in the last shell is not 8, and the shell is not full, and thus, chlorine is chemically unstable. To give an example of a chemically stable element, Argon has 8 atoms in its last shell, which is why it is chemically stable and therefore does not react with any element.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
Why is chlorine diatomic?
A lone chlorine atom has 7 outer shell electrons, 1 electron short of a full outer shell of 8 electrons, which is stable. In order to achieve this full outer shell two chlorine atoms share a pair of electrons, with each atom contributing 1 electron to the pair. By sharing electrons in this manner the chlorine atoms achieve a full outer shell.

Argon has three full shells of electrons. Elements react to form bonds so that their outer shell is full. As Argon has a full outer shell it is unreactive
In chlorine the outer energy level contains 7 electrons To attain stable state the chlorine atom needs to gain how many electrons?
Just one. To become stable, it needs eight electrons; a full outer shell.

Why does chlorine have a negative charge?
Chloride forms a negative ion because of its number of valence electrons. Chloride wants to have 8 valence electrons. It only has 7. So for Chloride to have a full electron shell it accepts an electron from other elements. Because electrons have a negative charge, the extra electron that Chloride receives gives it a negative charge.
Is chlorine more reactive than neon?
Yes, Neon is a noble gas (its outer shell of electrons is full) and does not react with anything, while Chlorine is a halide and is very reactive.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
What would be the charge of a beryllium atom that has a full outer shell?
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
An element is inactive if?
It has a full outer shell of electrons.
Is the outer shell of argon full?
Yes it is . The outer argon is full becoz it has 18 electrons
