'OXIDATION'
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
Oxygen gains 2 electrons to become an oxide ion (O2-).
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
These reactions are called redox reactions, where one atom or molecule loses electrons (oxidation) and another gains electrons (reduction). The atom or molecule that gains electrons is called the oxidizing agent, while the one that loses electrons is the reducing agent. This electron transfer leads to a change in oxidation states of the atoms involved.
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
Oxygen.
Oxygen gains 2 electrons to become an oxide ion (O2-).
losses electrons
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
An oxygen atom gains 2 electrons when it becomes an ion because it wants a full valence shell (as in, its outer energy level is trying to reach 8 electrons).
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
4 down, Reduction.
An oxygen anion has 10 electrons, because it gains two electrons to achieve a full valence shell of 8 electrons.
