Chemical electron shell 5, what is the electron shell structure?

It's a good thing upstairs.

I add the following, if it is the nth layer, then the maximum number of electrons is 2*n*n.

Electron layerThe structure is the same master in atomic physicsQuantum numbernAtomic orbitalsLayout. The electron layer structure is the arrangement of a group of atomic orbitals with the same principal quantum number n in atomic physics.

The electrons in an atom are each in a definite energy state represented by two quantum numbers, and the electronic shell is a collection of all electronic states with the same given principal quantum number (or with the same given principal quantum number and the same given orbital angular momentum quantum number).

Definitions:

Henry Mosley and Backella first discovered the electron shell in experiments with X-ray absorption. Bacla referred to them as the electron shells such as k, l, and m (in English order of the sons) (originally the K and L electron shells were named b and a, but the reason for the change to k and l was to reserve vacancies for the undiscovered electron shell). These letters were later replaced by n-value rolling fingers, etc.

The name electronic shell originates from the Bohr model, in which electrons are thought to rotate around the core at a specific distance in groups, so the trajectory forms a shell. Electrons are in the nucleus.

When arranging the electrons, the energy of the electrons should be as low as possible.

According to the relative level of the atomic orbital energy level, it can be divided into several electronic shells, k, l, m, n, o, p, q...Bacla did this in order to make room for the undiscovered electron layer. From k to k, k, l, m, n, o, p, q...

The electronic shell, also known as the energy shell and electronic shell, is a group of atomic orbitals with the same principal quantum number n in atomic physics. The electron shell cannot be understood as the movement of electrons in a thin layer of space outside the nucleus, but is divided by the region with the highest probability of electron occurrence and distance from the nucleus.

The electron shell is made up of the electron order of an atom. This can prove that the maximum number of electrons that can be accommodated in the electron shell is 2N2, and the X-ray absorption work of Henry Mosley and Bacclera was the first to discover the electron layer experimentally. Bacla referred to them as the electron shells such as k, l, and m (in English order of the sons) (originally the K and L electron shells were named b and a, but the reason for the change to k and l was to reserve vacancies for the undiscovered electron shell).

These letters were later replaced by n-values, etc. They are used in the Sigban notation method for beamsplitters.

<> atom, electrons move around the nucleus and can only move in certain discrete regions of motion, known as discrete orbits, or electron shells. The first shell is closest to the nucleus and has the greatest gravitational pull and can hold up to 2 electrons. The second shell is the second closest to the nucleus and can hold 8 electrons, and the third, fourth, and fifth layers can hold 8, 18, and 18 electrons in turn.

The electrons are sequentially filled into the electron shell, and if the outermost orbital of an atom is completely filled with electrons, it is chemically inactive and generally does not undergo chemical reactions (see Noble Gases). If the outermost shell of an atom is unsaturated, it is easy for a chemical reaction to saturate, gaining or losing electrons from other atoms. This electron exchange is mainly carried out in two ways and results in the formation of two chemical bonds between the atoms:

When an atom donates an electron to another atom, the chemical bond formed is calledIonic bonds。When two atoms share the same electron pair, the chemical bond formed is calledCovalent bonds

In a covalent bond, if the attraction of the nuclei of two atoms to the electron pairs is very different, the electron pairs are biased, which is called a polar covalent bond. Conversely, if the difference is not large, a non-polar covalent bond is formed.

For electrons are in different energy level states in atoms.

The electron shell is a group of atomic orbitals with the same principal quantum number n in atomic physics. Electrons are in different energy level states in atoms, so the electron shell is also called the energy layer. The electron shell is available n(n....) indicates that n=1 indicates the first electron shell (k layer), n=2 indicates the second electron shell (l layer), and then n=3 and the electron shell indicate the third (m layer), the fourth (n layer), and the fifth (o layer).

As the value of n increases, i.e., by k, l, m, n, o....The energy of the electrons gradually increases, and the average distance of the electrons from the nucleus increases. The maximum number of electrons that can be accommodated in the electron layer is 2N.

Atomic structure and electron shell ** solution.

The number in the figure represents the smallest unit of indivisible positive and negative electromagnetic information - qubits (qubits) by the famous physicist John. Wheeler John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

The L shell has one more electron than the K layer, then there are 2 in the K shell and 3 in the L layer, so it is boron.

The L layer has one more electron than the M layer, then the M layer cannot have more than 8 electrons, and the L layer already has 8 electrons, so the M layer is 7 electrons, so it is chlorine.

After the reaction is BCL3, which has an empty 2p orbital, so it is Lewis acid.

Strictly speaking, no.

Atomic structure includes the nucleus and extranuclear electrons.

So draw the nucleus, indicate the number of nuclear charges, and then draw the electron configuration outside the nucleus.

Because, after all, the number of nuclear charges determines the type of element.

The extranuclear electron configuration of many particles (atoms, ions) is the same.

Electrons are in different energy level states in atoms, roughly speaking, they are distributed in layers, so the electron shell is also called the type regression energy layer.

The electron shell is available n(n....) indicates that n=1 indicates the first electron shell (k layer), n=2 indicates the second electron shell (l layer), and n in turn indicates the third (m layer), the fourth (n layer), and the fifth (o layer).

Generally, with the increase of n value, i.e., by k, l, m, n, o....In the order, the energy of the electron gradually increases, and the electron separates from the nucleus.

The average distance is also getting larger. The maximum number of electrons that can be accommodated in the electron layer is 2N.

1. Electrons are elementary particles.

It is currently no longer possible to decompose into smaller substances, which are times the diameter of a proton and weigh 1 or 1836 of a proton.

2. Electrons move at high speed around the nucleus of atoms, and electrons are usually arranged on various energy layers, and when atoms combine with each other to become molecules, electrons in the outermost shell will move from one atom to another atom or become electrons shared with each other.

3. This is made by Ireland.

It was proposed by physicist George Din Stoney in 1891.

4. The classification of electrons belongs to the leptonon class of subatomic particles, and leptons are considered to be one of the basic particles that make up matter, that is, they cannot be decomposed into smaller particles.
