A stable configuration with two electrons typically refers to a system in which the electrons occupy the same energy level or orbital, such as in a helium atom. In this case, the two electrons are paired in the 1s orbital, where they have opposite spins, allowing them to coexist due to the Pauli exclusion principle. This pairing minimizes their energy and creates a stable arrangement. Additionally, the effective nuclear charge attracts the electrons, further contributing to the stability of the atom.

How many electrons does barium lose to become a stable octect?
Two electrons.
Have two valence electrons and get to a stable electron configuration by using two electrons?
You can achieve a stable electron configuration by using two electrons by forming a covalent bond with another atom that also has two valence electrons. In this way, each atom can share its valence electrons to achieve a full outer shell and achieve stability.
How many valence electrons does Beryllium need?
Beryllium (Be) has two valence electrons in its outer shell. To achieve a stable electron configuration, it typically forms compounds by sharing or losing these two electrons. Therefore, Beryllium does not need any additional valence electrons; it is stable with the two it has.
What two elements only need two valence electrons to be happy?
The two elements that only need two valence electrons to achieve a stable electron configuration are helium (He) and beryllium (Be). Helium, being a noble gas, has a full outer shell with two electrons, making it stable. Beryllium, a metal, typically forms compounds by sharing or losing its two valence electrons to achieve a stable state, similar to that of helium.
How many electrons would an atom of carbon need to have to be a negative ion?
There are six electrons in two shells.In order to stable carbon, it take electrons from nearest noble gas to stable the carbon.It order to stable carbon it gain -4 electrons from the nearest noble gas Neon.
Is an atom stable if it has two electrons in the third shell?
No - it would want to lose these two electrons

How many electrons can oxygen lend?
Oxygen can lend two electrons to form a stable compound. Oxygen typically forms bonds by accepting two electrons to complete its outer shell and achieve a stable electron configuration.
Does xenon gain or lose electrons to be a stable octet?
Neither. It has a stable octet in its ground state.
How many electrons does selenium need to lose or gain to be stable?
Selenium needs to gain two electrons to achieve a stable electron configuration. By gaining two electrons, selenium will have a complete outer energy level (valence shell), which is the most stable configuration for an atom.
How many electrons does an atom need in its outer energy level to be stable?
Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.
Are free electrons stable?
No. Free electrons are not stable.
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
