There are two notations.
The classical notation: 2.8.8.18.18.22
The Quantum notation: [Xe]6s^2 4f^14 5d^6 (spaces added for ease of reading only)
An unoccupied orbital is represented by an empty box in orbital notation. It does not have any electrons present in it but is available to accept electrons if needed.
The orbital notation for vanadium is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
The element with this orbital notation is nickel (Ni), a transition metal.
The polyatomic ion oxide is O2-, which consists of two oxygen atoms with a charge of -1. This ion is commonly found in compounds such as magnesium oxide (MgO) and carbon dioxide (CO2). Oxoanions containing oxygen and other elements can also form polyatomic ions with the oxide ion.
O2- ion is known as peroxide in English. As it is not a transition metal ion, it is not able to be written any other way. If it were a transition metal such as Lead (Pb), the Pb4+ ion can be called lead (IV) or plumbic. Lead (IV) is written in the Stock method with roman numerals representing the electrons in the ion. Plumbic is written in the Classical method with the suffixes "ic" and "ous". As some transition metals have two different ions, "ic" is added to the higher ion name while "ous" is added to the lower ion name.
The orbital notation for thallium is [Xe}4f14.5d10.6s2.6p1.
In orbital notation, electron placement is represented by arrows within individual orbitals, while electron configuration represents the distribution of electrons among the orbitals in an atom or ion using a numerical system of energy levels. Orbital notation provides a visual representation of electron distribution within an atom or ion, while electron configuration provides a standardized way to express the distribution of electrons throughout an atom.
The chemical formula of hydronium ion is (H3O)+.For the "oxide ion" check your spelling.

The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.
The formula for the oxide ion is O2-, and the formula for the nitrate ion is NO3-.
An unoccupied orbital is represented by an empty box in orbital notation. It does not have any electrons present in it but is available to accept electrons if needed.
The orbital notation for vanadium is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
The noble gas that is isoelectronic with the oxide ion O2 is neon (Ne). Both the oxide ion O2 and the neon atom have 10 electrons.
The element with this orbital notation is nickel (Ni), a transition metal.
