Why are neon and argon placed in Group 18?

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive.

What is the official group family name for Ar Argon )? *?

Argon belongs to the noble gases (also known as the inert gases). They form the right-most column of the periodic table and are known as group 8 or group zero.

What is Group 18 on the periodic table?

noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

What element has 18 protons and 22 neutrons?

Argon
Given the number of protons is \[18\]. So, the atomic number is also \[18\], and the element with atomic number \[18\] is Argon with the symbol \[Ar\]. Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons.

Why does ar not form Ar2?

We know that argon is a noble gas. Also all noble gases are monoatomic gases meaning having only one atom in one molecule. And even these gases have valency as 0. Therefore Argon cannot form Ar2 molecule.

Why argon is not Ar2?

Since the atoms of argon contain eight electrons in their valence shell they are stable and do not participate in bonding. So Argon do not form Ar2 molecules.

Which of the following belongs to Group 18?

Answer: (C)Ar i.e. Argon is a Noble gas. And all the noble gases falls under group 18. Other Noble gases are:- Helium, Neon, Krypton, Xenon, Radon and Organesson.

Does argon have similar properties to group 18 elements?

These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

Is Group 18 A metal?

Group 18 of the periodic table contains the noble gases. These are the elements in the 18th column of the periodic table, at the far right. They are all nonmetals, and are found in their standard state as monatomic gases.
