May 23, 2024 · O2- has 10 electrons. Each oxygen atom contributes 8 electrons, and since there are two oxygen atoms in O2-, the total number of electrons is 16.

The ion O2 has 8 protons. Each oxygen atom contains 8 protons in its nucleus, and since there are two oxygen atoms in the O2 ion, the total number of protons is 8 x 2 = 16.

Dec 16, 2024 · The oxide ion O2- has gained two electrons compared to a neutral oxygen atom. The electron configuration of oxygen is 1s2 2s2 2p4.

May 23, 2024 · The thing that separates one element from the other is how many protons the nucleus has. It doesn't matter what the superscript is. Therefore O2- will have 8 protons but 10 …

May 30, 2024 · O2- is neither an acid nor a base. It is the oxide ion, which is a basic or alkaline species due to its ability to accept a proton.

Jun 16, 2024 · The notation for an oxygen ion depends on the specific charge of the ion. For example, the notation for the oxide ion (O2-) is O2-.

Jun 17, 2024 · The "O" stands for oxygen, and the "2" indicates that there are two oxygen atoms in the molecule. Therefore, "O2" represents a molecule of oxygen gas made up of two oxygen …

May 25, 2024 · The O2- ion is larger than the O atom because the extra electron in O2- causes repulsion between electrons, leading to an increase in atomic size compared to the neutral O …

Jun 6, 2024 · The ionic radius of N3- is larger than that of O2- because the extra electron in the N3- ion is located in a higher energy level, leading to larger electron-electron repulsions and …

May 21, 2024 · The charge on an oxygen ion is typically -2. Oxygen atoms tend to gain two electrons to achieve a full outer shell, resulting in the formation of the O^2- ion.
