the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
Atoms can lose or gain electrons. When they do, they form charged particles called ions: if an atom loses one or more electrons, it becomes a positively charged ion, I think ;]
When atoms lose or gain an electron, they become ions. If an atom loses an electron, it becomes positively charged and is called a cation. If an atom gains an electron, it becomes negatively charged and is called an anion.
If an atom gains an electron, it becomes an anion, which is negative. Anions are larger than the original atom because of the added electrons. N + electron(-) --> N(-) If an atom loses an electron, it becomes a cation and positively charged. Cations are smaller than the original atom because of the lost electrons. N(2+) = cation
When an atom gains or looses a valence electron it becomes a charged particle called an ion
When an atom loses an electron, it becomes positively charged and is referred to as a cation. Conversely, if an atom gains an electron and becomes negatively charged, it is called an anion. Anions are typically formed by nonmetals, which tend to gain electrons to achieve a full valence shell.
The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
Sodium loses its one valence electron to become Na+
If an atom loses an electron, it becomes positively charged (cation) due to having more protons than electrons. If an atom gains an electron, it becomes negatively charged (anion) due to having more electrons than protons. This change in charge affects the atom's chemical properties and ability to form bonds.
An oxygen atom only forms two covalent bonds with a hydrogen atom because oxygen needs to gain two electrons to achieve a stable electron configuration, similar to the noble gas configuration. By sharing one electron with each hydrogen atom, oxygen can fulfill its octet and achieve stability.
