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.
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.
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
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.
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
Yes, neutral unbonded atoms can complete a valence octet by gaining or losing electrons to achieve a stable electron configuration with 8 valence electrons. This stability is known as the octet rule, which applies to many elements in the periodic table.
Sulfur, with its 6 valence electrons, will gain 2 electrons to achieve a stable octet configuration, resulting in a charge of -2.
Fluorine needs one additional electron to satisfy the octet rule, giving it a total of 8 valence electrons and achieving a stable electron configuration.
You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
A chloride ion has 18 electrons, giving it a valence of -1.
