All the Noble/Inert gasses.
However, Helium (He) has a complete outer shell of only TWO(2) electrons.
The other noble gases all have a complete octet (outer) shall, of EIGHT(8) (Octet) electrons.
What else can I help you with?
Elements with complete outer shells?
Elements with complete outer shells have a full valence shell of electrons and are stable. This configuration is typically achieved by having eight electrons in the outer shell (known as the octet rule) or two electrons for the first shell. These elements are generally inert or have low reactivity due to their stable electron configuration.
What element on the periodic table had complet outer shells give the name and symbol for each?
All of the elements in group 18 have complete outer shells, and are called the noble gases. They are helium, He, neon, Ne, argon, Ar, krypton, Kr, xenon, Xe, and radon, Rn.
Which elements have three shells?
There are either two He and Ne. These are truly complete as there are no more empty orbitals in their outer shells. If you allow argon it has 3d orbitals empty and then so do the rest of the noble gases, so there would be more than 3.
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
What are elements with full outer electron shells called?
Elements with a full outer electron shells are usually found in group 18/8 on the periodic table, also known as 'Noble Gases'. But during a chemical reaction the element may gain or lose electrons in order to become stable. These atoms are called 'Ions'
Where are elements with full outer shells located on the periodic table?
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
What elements had complete outer shells and why?
Group 0

What do elements in the same periodic. Have in common?
They have the same number of occupied energy levelsthey all have the same amount of outer shells for the atom
Which elements have three shells?
There are either two He and Ne. These are truly complete as there are no more empty orbitals in their outer shells. If you allow argon it has 3d orbitals empty and then so do the rest of the noble gases, so there would be more than 3.
What elements have outer shells?
protons
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
What element would have a full valence shell on the periodic table?
The noble gases helium and neon are the only elements with completely full outer shells.
