What is the electronic structure of oxygen? Electronic and structural formula of oxygen

The molecular orbital formula of O2 is.

kk(σ2s)2(σ*2s)2(σ2p)2(л2py)2(л2pz)2(л*2py)1(л*2pz)1

In the O2 molecule, the bonded (2P)2 constitutes a bond.

2py)2 and (*2py)1 constitute a three-electron bond, and (2pz)2 and (*2pz)1 constitute another three-electron bond, so there is one bond and two bonds in the O2 molecule, and its structural formula. can be written.

o-o: or.

o---o:

o---o Explain that is. It represents the three electron bonds, the horizontal lines represent the bonds, and the small dots at the left and right ends represent the 2s pairs of lone electrons.

The 2S lone pair of electrons is obtained by canceling each other out of bonding (2S)2 and antibonding (*2S)2, the activity of the O2 molecule has a certain relationship with its presence of three electrons (electrons are not paired, the molecular orbital is not full), and the bond energy of O2 is only.

The outer electronic structure of the O2 molecule is 2S22P4, so there are 12 electrons filled into the O2 molecular orbital, and the last two electrons are not filled together in *2py or *2pz, but in both of them, which is determined by the Hund rule, so there are two unformed electrons with parallel spins in the O2 molecule, this fact successfully explains the magnetic properties of the O2 molecule, if according to the valence bond theory, oxygen bonding is.

Colorless and odorless gas, oxygen element.

The most common elemental form. Melting point, boiling point -183 . Not easily soluble in water, 1L of water dissolves about 30ml of oxygen. In the air, oxygen accounts for about 21%.

In a chemical reaction, it is generally the outer electrons of the atom that change. For the sake of simplicity, black dots are often used around element symbols in chemistry"and fork" to denote the outermost electrons of the element's atom.

The formula of the substance represented in this way is called the electronic formula. However, the electronic formula of the classical 8-corner body learned in middle school is an outdated theory that can only be used to represent a small part of the matter formed by the main group elements, and cannot be used to represent the transition elements.

The substances that form the traced segment do not correctly represent the structure of many common substances.

Hi! The electronic formula of oxygen is O2. It denotes the union of two oxygen atoms in an oxygen molecule.

Each oxygen atom has 6 outer electrons, whereas each oxygen atom in the oxygen molecule shares two electrons with another oxygen atom, forming a covalent bond. This makes the oxygen molecule very stable.

In the electronic formula, the letter o stands for the element oxygen, and the number book pure 2 means that there are two oxygen atoms. This structure forms the common gaseous state of oxygen. Oxygen is one of the gases we need for breathing and is an important component of many chemical reactions and biological processes.

High-powered answers. Electronic: O2; Structural Formula:

o：o。The four electrons in the middle of oxygen are shared to form a covalent double bond, which forms a stable structure with the other four electrons of its own.

The oxygen atom has a total of 8 electrons, with the outermost six electrons; In order to achieve the stable structure of the outer 8-electron junction, it is necessary to form common electron pairs with other atoms of the perturbation liquid. Oxygen is paramagnetic, indicating that there are single electrons in the molecule, which needs to be described in terms of molecular orbitals. Two oxygen atoms undergo sp orbital hybridization, one single electron is filled into the sp hybrid orbital and bonded, and the other single electron is filled into the p orbital and bonded.

Oxygen PropertiesPhysical properties of oxygen: Normally, oxygen is a colorless and odorless gas, which is slightly denser than air and is not easily soluble and balanced in water. Under certain conditions, it can be liquefied into a light blue liquid or solidified into a light blue solid.

The fact that fish and shrimp in rivers and seawater can survive indicates that there is oxygen dissolved in the water in nature. Chemical properties of oxygen: Oxygen is a chemically reactive gas, which provides oxygen in the oxidation reaction, has oxidizing properties, and is a common oxidizing agent.

The electronic formula of oxygen is O2. Oxygen is a molecule formed by two oxygen atoms (O) by sharing electrons. In the oxygen molecule, two sail oxygen atoms are stably bound together by sharing two pairs of electrons to form a double bond of oxygen.

Therefore, the chemical formula of oxygen is O2, which represents a molecule composed of two oxygen atoms together.

The electronic formula of oxygen can be expressed as O2 2-

This means that the oxygen molecule (O2) has 2 negative charges (-), that is, it accepts 2 electrons. Oxygen molecules usually exist in the form of diatoms, each oxygen atom shares two pairs of electrons with another oxygen atom, and two pairs of electrons are present in the covalent bond formed, so the oxygen molecule has a total of 4 pinned coarse electrons. When the oxygen molecule receives two extra electrons, the electronic formula of oxygen changes to O2 2-.

Such a chemical state can also be expressed in the form of oxygen ions (O2-).

The chemical difference of oxygen is O2. This means that there are two chains of this oxygen atom in each oxygen molecule, and they share two pairs of electrons to form a virtual oxygen molecule. Thus, O2 is a molecule made up of two oxygen atoms, also known as an oxygen molecule.

The oxygen electronic formula is:
