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
NO!!! Atom is formed by the gain/loss of electrons. When an atom gain/loses electrons it is an ION NOT an atom. NB A positively (+) charged ion is a CATION A negatively (-) charged ion is an ANION .
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.
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.
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
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.
Sodium loses its one valence electron to become Na+
