What 3 elements on the periodic table had complete outer shells?
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 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.
What elements have complete outer energy levels and will bond with any other element?
Elements with complete outer energy levels are noble, which means that they will not bond with other elements. They are not (normally) reactive.
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'
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 had complete outer shells and why?
Group 0
What 3 elements on the periodic table had complete outer shells?
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.
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 have outer shells?
protons
Why are least reactive elements not so reactive?
The least reactive elements are the noble gases (helium, neon, krypton, argon, xenon). They each have a complete outer electron shell (two electrons for helium, eight electrons in the outer shell of the other noble gases). Chemical reactions take place in ways that result in making outer electron shells more complete (or for transition state elements, it can also make inner shells more complete), so if the outer electron shell is already complete, there is no basis for a chemical reaction.
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.
What is a group of elements that rarely combine with other elements because they already have eight electrons in their outer shells?
A group of elements that rarely combine with other elements because they already have eight electrons in the outer shells is a Noble Gas
What kind of outer energy shell do elements in family 18 have?
The outer energy shells in the group 18 elements, called the noble gases, have a complete octet of ns2np6, where n is the highest energy level. The only exception is helium, which has an outer energy shell of 1s2.
What is the Family name for elements that have filled energy levels and do not make compounds?
Nobel gases. They are stable elements in that they have complete outer shells, but they can be made to react with other elements to form compounds. For elementary chemistry, however, they can be considered inert.Ray
What is unique about noble gasses?
The Noble Gas are Non-Reactive, they do not form bonds with other Elements. ***** They don't form bonds at all because their outer shells are complete.
Why are alkali metals active?
because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.
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
