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'
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.
How do the inner electron shells differ from an atom's outer electron shells?
Inner electron shells are closer to the atomic nucleus and have lower energy levels compared to outer electron shells. Outer electron shells are farther from the nucleus and have higher energy levels, making them more involved in chemical reactions and bonding with other atoms.
How many electron shells does chromium have?
Chromium has two electrons in the outer most shell.
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.
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
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 has a full outer electron shells which makes them inert?
All noble gases or group 18 elements.

Inner electron shells are closer to the atomic nucleus and have lower energy levels compared to outer electron shells. Outer electron shells are farther from the nucleus and have higher energy levels, making them more involved in chemical reactions and bonding with other atoms.
What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens typically contain seven electrons, making them highly reactive and likely to gain one electron to achieve a stable electron configuration. Additionally, halogens have a tendency to form negatively charged ions when they react with other elements by gaining one electron.
How many electron shells does chromium have?
Chromium has two electrons in the outer most shell.
How are the electron clouds of the atoms of the elements in a group the same?
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
What elements have outer shells?
protons
Why are He and Ne called noble gases?
They do not react very much with anything (their outer electron shells are full)
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
What is more stable partially filled or full electron shells?
Full electron shells are more stable than partially filled ones because they have achieved a more energetically favorable configuration with a lower overall energy. Partially filled shells are more likely to interact with other atoms to either gain or lose electrons in order to achieve a full shell configuration.
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
