What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
How many electrons do you need to become a noble gas?
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
Name the noble gas withe the smallest atomic number?
The noble gas with the smallest atomic number is helium, with an atomic number of 2.
Which noble gas has the greatest atomic number?
That would be Astatine with the atomic number 85.
What gas has a number of 18?
Argon, one of the noble gases.Argon - which is a noble gas, has atomic number 18.Argon - which is a noble gas, has atomic number 18.
How can elements acquire a stable atomic structure like that found in a noble gas?
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
How many electrons does n need to gain to becom isoelectronic with a noble gas?
An atom with atomic number n needs to gain enough electrons to have the same number of electrons as the nearest noble gas in the periodic table. This would typically involve gaining 8 electrons to achieve the stable electronic configuration of a noble gas.
In the periodic table which noble gas has 2 electrons?
It is helium. It's atomic number is 2, so it has 2 protons and therefore 2 electrons.
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What is the formula of argon gas?
Argon is an element. Symbol: Ar Atomic Number: 18 Family: Noble Gases Val Electrons: 8
What is the alkali metal ion that would have neon as its noble gas configuration?
Sodium ion (Na+) and neon will have the same number of electrons
Why sodium and magnesium form positive ions?
Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.

What would be the atomic number of the noble gas after radon?
The atomic number of the noble gas after radon is 118, which corresponds to oganesson.
