Which elements have a full outer shell of electrons?
Group 0 elements – helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn) – have full outer shells. (Group 0 is sometimes called Group 8 – all the elements in the group have eight electrons in their outer shell, except for helium which only has two).
What family has a full outer shell?
noble gases
The group (family) with elements cotaining full outer shells are the right-most group on the table: the noble gases: helium, neon, argon, krypton, xenon, and radon (element 118, oganesson, also belongs in this group, but most all of its chemical and physical properties are as of yet unknown.
What is a full shell of outer electrons?
A full outer shell is known as the noble gas configuration where the outer shell of an atom is energetically stable and contains 8 outer electrons.
Which of the following element has its outermost shell filled?
Explanation: All elements in group 18 (8A) (all the elements above and below Ne on the periodic table) have their outer shell completely filled. They are the noble gases.
Does helium have a complete outer shell?
In this table, you can see that helium has a full valence shell, with two electrons in its first and only, 1n, shell. Similarly, neon has a complete outer 2n shell containing eight electrons. These electron configurations make helium and neon very stable.
Why is a full outer shell stable?
The properties of an element are determined by its outermost electrons, or those in the highest energy orbital. Atoms that do not have full outer shells will tend to gain or lose electrons, resulting in a full outer shell and, therefore, stability.
What kind of elements have a natural full outer shell of electrons?
What group of elements have a natural full outer shell of electrons? The group (family) with elements cotaining full outer shells are the right-most group on the table: the noble gases: helium, neon, argon, krypton, xenon, and radon (element 118, oganesson, also belongs in this group, but most all of its chemical and physical properties are as
What are the noble gases with a full outer shell?
The group (family) with elements cotaining full outer shells are the right-most group on the table: the noble gases: helium, neon, argon, krypton, xenon, and radon (element 118, oganesson, also belongs in this group, but most all of its chemical and physical properties are as of yet unknown.

What kind of electron shell does neon have?
This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full. Similarly, neon has a complete outer 2n shell containing eight electrons.
Which is most reactive when its outermost electron shell is full?
In general, atoms are most stable, least reactive, when their outermost electron shell is full. Similarly, neon has a complete outer 2n shell containing eight electrons. Hereof, which of the following elements is usually nonreactive because of its full outer electron shell?
