Atoms with full outer electron shells are more stable. The atoms (elements) with full outer electron shells are the noble (sometimes called inert) gases. These are the elements in Group 18 of the Periodic Table, and you know them as helium, neon, argon, krypton, exnon and radon.

Why the electron affinities of beryllium and nitrogen are positive?
In general, elements attract electrons because they have positively charged nuclei, and although they also have negatively charged electron shells, the electrons are very mobile and they adjust themselves so that they have the minimum effect on other electrons while remaining as close as possible to the nucleus (a constant balancing act). The specific degree to which a given element will attract electrons is strongly influenced by the kind of electron configuration that the element has. Nitrogen, which can form a complete outer shell by acquiring another 3 electrons, has a much stronger attraction for electrons than beryllium has, since beryllium can more easily get to a complete outer shell by losing electrons than it can by gaining them.
Why is the electron configuration for copper 3d10 4s1 - shouldn't it be 3d9 4s2?
Copper has a partially filled d orbital to achieve greater stability. Hence, it gives up one electron from the 4s orbital to make the 3d orbital completely filled with 10 electrons, which is a more stable configuration. This results in the electron configuration of 3d10 4s1 for copper rather than 3d9 4s2.
What do a beryllium ion and neon atom have in common?
Well, isn't that just lovely? Both a beryllium ion and a neon atom have something special in common - they both have filled electron shells. Isn't it just wonderful how nature creates balance and harmony in the smallest of things? Just like when we add a touch of white to our painting to bring everything together.
How many electrons do barium need to lose to become stable?
Barium, with an atomic number of 56, needs to lose 2 electrons to achieve a stable electron configuration, similar to a noble gas. This is because barium will then have a filled outer electron shell, following the octet rule.
What is the result of sodium atom transferring an electron to a chlorine atom and they become stable?
The result is what you use to put in the food. Table salt (or sodium chlorine). It's a very stable compound, as each of the ions have their orbitals completely filled. Recall that in their normal states, Sodium has only one valence electron, and the Clorine is missing one to have its orbitals filled.
Are atoms most stable when they have partially filled shells?
No, atoms are most stable when their outermost electron shells are completely filled. This is because a full outer shell results in a lower energy state, making the atom more stable. Partially filled shells can lead to greater reactivity as atoms seek to fill or empty their outermost shell.
What are stable electron configurations are likely to contain?
completely filled valence shells
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
Why does an atom want to be stable?
Atoms want to be stable because stability leads to a lower energy state, which is more favorable. When atoms are stable, their outer electron shells are filled or partially filled, which results in a more balanced state. Atoms achieve stability by gaining, losing, or sharing electrons to reach a more stable electron configuration.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
Does a partially filled outer electron level make an atom stable?
A partially filled outer electron level does not necessarily make an atom stable. Stability often depends on achieving a full outer electron level through gaining, losing, or sharing electrons to reach a stable configuration, such as the octet rule for main group elements.
Is Materials with a partially filled valence ring are said to be chemically stable?
Materials with a partially filled valence ring are typically more chemically reactive rather than stable. A partially filled valence ring indicates that the material has unpaired electrons, which can easily participate in chemical reactions to achieve a more stable electron configuration. In contrast, materials with completely filled valence rings tend to be more chemically stable because they have achieved a full outer electron shell, making them less likely to react with other substances.
What are stable electron configurations most likely to contain?
Stable electron configurations are most likely to contain filled energy levels or filled subshells. These configurations generally follow the octet rule or duet rule, depending on the element. Additionally, stable electron configurations may contain configurations with a full valence shell of electrons.
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
Filled energy sublevels are more than partially filled sublevels?
Correct. Filled energy sublevels have electrons occupying all available orbitals within the sublevel, while partially filled sublevels have some orbitals unfilled. This is a result of the rules governing electron configuration in atoms.
Some elements are highly what because their outermost energy levels are only partially filled?
Some elements are highly reactive because their outermost energy levels are only partially filled, and they seek to gain or lose electrons to achieve a stable electron configuration. This can lead to the formation of chemical bonds with other elements in order to reach a more stable state.
Which family has the correct electron configuration to be stable?
The family of 'noble' (= inert) gasses in group (column) 18 of the periodic table. Their valence shell is completely filled up with s2 and p6 electrons.
