When the number of protons in an atom exceeds 18, how is it arranged?

First of all, we should clarify a few concepts: nuclear charge number = atomic number = proton number = number of electrons outside the nucleus (1) The electrons outside the nucleus are always arranged in the electron shell with the lowest energy (closest to the nucleus) first, and then in the electron shell with higher energy from the inside to the outside; (k, l, m, n, o, p, q) (2) The maximum number of electrons in each electron layer is 2n2; (3) the outermost shell does not exceed 8 electrons (only the first shell is up to 2 electrons); The subouter shell does not exceed 18 electrons, and the penultimate shell does not exceed 32 electrons. The formula is:

The first shell is 2, the second shell is 2n2 after the penultimate shell, the penultimate shell does not exceed 32 electrons, and the outermost shell does not exceed 8. The schematic diagram of Fe (+26), BA (+56), Hg (+80) is as follows: +26 2 8 14 2

Sorting: Molecule > Atom > Negative Ion > Positive Ion > Proton = Neutron > Electron.

A molecule is made up of two or more atoms; An atom contains a nucleus, there are protons and neutrons in the nucleus, the protons have positive potential, the neutrons are not charged, the neutrons and protons are the same size, the number of neutrons and protons is equal or slightly different, and there are particles outside the nucleus that have electrons moving in an irregular circle around the nucleus, with negative potential, and the number is equal to the number of protons.

Ions: When an atom gains or loses electrons, it is called an ion, the atom that gains an electron is called a negative ion, and the atom that loses an electron is a positive ion.

Quantum: In the microscopic realm, the change of certain physical quantities is carried out in leaps and bounds in the smallest unit, rather than continuous, and this smallest unit is called quantum, which is also a general term for the basic units of matter such as atoms, electrons, and photons.

Molecules, atoms, protons, neutrons, electrons, quantum, ions are all particles.

Molecule "Atom" Negative Ion "Positive Ion" Proton = Neutron "Electron".

You dare to say anything upstairs.

None of the concepts are right, if you don't know, check it out, don't be mistaken if people know how many atoms the noble gas molecules are made of?

Do you know carbonate, sulfate, nitrate... How many atoms is plasma made of?

Is quantum a basic unit?

Which is bigger, molecule, atom, or negative ion? Is the hydrogen cation or proton bigger?

None of them were right!

The arrangement from small to large is:

Electrons, protons, atoms, and molecules are closed.

The approximate dimensions are:

1. Radius size of electrons: traditional size: x 10 (-15) m modern size: 10 (-22) m

2. The radius size of the proton: x 10 (-15)3. The semi-longitude size of the atom: 10 (-10) m

4. The size of the half-smile diameter of the molecule: it is widely distributed, please refer to the figure below.

Molecules, atoms, protons (or neutrons), electrons.

First of all, we must clarify a few concepts: the number of nuclear charges = atomic number = the number of protons = the number of electrons outside the nucleus, and the general law of the arrangement of extranuclear electricity.

1) Electrons outside the nucleus are always arranged in the electron shell with the lowest energy (closest to the nucleus) first, and then in the electron shell with higher energy from the inside to the outside. (k、l、m、n、o、p、q)

2) The maximum number of electrons held in each electron layer is 2n2;

(3) the outermost shell does not exceed 8 electrons (only the first shell is up to 2 electrons); The subouter shell does not exceed 18 electrons, and the penultimate shell does not exceed 32 electrons.

The formula is: the first shell is 2, the second shell is 2n2 after the second shell, the penultimate shell does not exceed 32 electrons, and the outermost shell does not exceed 8.

The schematic diagram of Fe (+26), Ba (+56), and Hg (+80) is as follows:

MNOP like Gong can just shoot the front of the sublayer, and the last layer is 2.

These are the common ones).

First of all, you have to know that the elements in the periodic table are divided according to what you say.

Since the number of protons in an atom is 19, it can be determined that this element is potassium.

Element A is the 19th element in the periodic table, since there are 19 self-made, it means that there are 19 electrons outside the nucleus, and the specific arrangement law is like this.

There are 4 electronic factories outside the nucleus, which are 2, 8, 8, 1 from the inside to the outside, which is the electronic arrangement law of the outer nucleus of element 19.

Go to the Internet to look up the "construction principle" diagram, the content of quantum chemistry.

I forgot what the law is ...

Study the Hundt rule well, the question is fairly simple!

Each electron layer can hold up to 2n squares, with no more than 2 outermost shells and no more than 8 subouter shells.
