Gains, Positive
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
Yes it will. Selenium has 6 valence electrons. If it accepts two more electrons to form Se2-, the resulting ion will have octet of electrons in the valence shell and will be stable.
When an atom or ion has 8 valence electrons, it is generally more stable, as it fulfills the octet rule. This stability is due to achieving a full outer electron shell, which is energetically favorable. Atoms or ions with fewer than 8 valence electrons may be more reactive, as they tend to gain or lose electrons to achieve a full octet.
A filled valence shell often has 8 electrons, which is called an octet. This configuration is considered stable because it mimics the electron configuration of noble gases, which have full valence shells.
It means that there are 8 electrons in the outer most shell of the atom. Atoms with 8 valence electrons are generally stable.
8 valence electrons
Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.
Neither. It has a stable octet in its ground state.
Octet Rule!
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
Oxygen needs to gain 2 electrons to reach an octet, as it has 6 valence electrons in its outer shell and requires a total of 8 electrons to have a stable octet configuration.
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
No, xenon cannot expand its octet because it is a noble gas with a stable electronic configuration of eight valence electrons.
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
The octet rule does not always refer to a stable arrangement of 8 valence electrons because some atoms can accommodate more than 8 electrons in their valence shell (expanded octet), such as elements in Period 3 and beyond in the periodic table. Additionally, some molecules, like radicals or species with an odd number of electrons, may not satisfy the octet rule but can still be stable due to resonance or other factors.
