Oxygen (O) has 8 protons and 8 electrons.
An element that needs three electrons to become stable is nitrogen. Nitrogen has five valence electrons and can gain three more electrons to achieve a full outer shell of eight electrons, making it stable.
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or stable.
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.

An element that needs three electrons to become stable is nitrogen. Nitrogen has five valence electrons and can gain three more electrons to achieve a full outer shell of eight electrons, making it stable.
The valence shell must be completed to eight electrons.
the element is stable.
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
Nobel gases are relatively nonreactive because they have eight electrons in the outermost energy level, which is a stable configuration
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
Oxygen.
Beryllium is a stable element.
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
An element can achieve a stable electron configuration by either gaining, losing, or sharing electrons to attain a full outer electron shell, usually with eight electrons, known as the octet rule. This helps the element to have a stable configuration similar to the nearest noble gas, making it more energetically favorable.
