1. There is no need to exchange it. It is the digital form of RMB. It's legal tender. It's compulsory circulation.
2.

Hello, according to your question, at present, there is no saying that RMB can buy digital currency, so this should not happen

For atoms: the number of electrons and protons is the number of elements. For example, h is element 1, which contains one electron and one proton

The neutron number should know the mass number. If you haven't learned this yet, the mass number can be simply regarded as the relative atomic mass, the number of neutrons = the relative atomic mass minus the number of protons. For example, if O is element 8, it has eight electrons and eight protons. Relative to the atomic mass of 16, the number of neutrons = 16-8 = 8

for ions, protons and neutrons are exactly the same as above, and electrons change, gain more and lose less. The method is similar

the number of electrons outside the nucleus = atomic number = proton number inside the nucleus = nuclear charge number (the number of electrons outside the nucleus of an ion = atomic number (sum) - charge number)

the maximum number of electrons held by each electron layer is 2n ^ 2 (n is the electron layer number). The number of electrons in the outermost layer is not more than 8 (when the k layer is the outermost layer, it is not more than 2). There are no more than 18 electrons in the second outer layer and 32 electrons in the last three layer

the extranuclear electrons are always arranged in the electron layer with the lowest energy first, and then from the inside to the outside, they are arranged in the L layer and then in the m layer. The above four laws are interrelated and cannot be understood in isolation

extended data:

neutrons exist in neutron stars as clusters (neutron stars are one of the few possible endpoints after supernova explosions e to gravitational collapse at the end of star evolution.) In the middle. The neutrons in the solar system mainly exist in all kinds of nuclei, and the neutrons in the elements are very rare β Decay is a change in which the neutron in the element releases an electron to become an element of the previous element sequence

Neutrons can be classified according to their velocities. High energy (high-speed) neutrons have the ability to ionize and penetrate deep into matter. Neutrons are the only ionizing radiation that can make other substances radioactive. This process is called "neutron excitation"“ "Neutron excitation" is widely used in the proction of radioactive materials in medical, academic and instrial fields

High energy neutrons can travel very long distances in air. Neutron radiation needs to be masked by hydrogen rich materials, such as concrete and water. Nuclear reactor is a common neutron source, and water is used as an effective neutron shield

arrangement rule:

1. The electrons are arranged in different layers from the nucleus to the nucleus, and the energy is from low to high

The maximum number of electrons in each layer is 2n2 (n is the number of electron layers)

There are no more than 8 electrons in the outermost layer (no more than 2 in the first layer), no more than 18 electrons in the second outer layer and no more than 32 electrons in the last three layers

In general, the electrons are always in the lowest energy layer, that is, the first layer, when the first layer is full, then the second layer, when the second layer is full, then the third layer

5. Box (enterprise digital asset safe) is a set of enterprise digital asset security solutions based on block technology. Based on the axiomatic technology of blockchain, cryptography, communication security and other fields, it realizes the seamless connection between technologies, and fundamentally solves the instry pain of private key theft and instruction tampering. At present, box mainly serves digital asset exchanges, digital asset investment institutions and related entrepreneurial teams.
6. Yes, just operate directly on the trading platform. Click to withdraw cash. Of course, this requires that the trading platform you are in is regular and has a regular license. For example, fire coin and Saturn exchange all have a regular license. These are easy to use.
7. Insomnia treatment to disease because of the key, clear specific causes, and then do targeted treatment. There are many ways to treat insomnia, such as psychological, physical, drug, traditional Chinese medicine and other methods, which can improve the phenomenon of insomnia. Different causes of insomnia, the treatment plan will also be different. You can go to the hospital for a comprehensive examination, identify the specific causes, and then choose the appropriate treatment plan. Daily must maintain adequate sleep time, can be in the appropriate exercise before going to bed or drink some honey water, can effectively alleviate insomnia.
8. I can exchange my ID card at the bank counter, within 50000 US dollars per person per year
if you are a foreigner, you can only exchange US $500 a day for one person. Domestic income can be exchanged with relevant supporting materials. The amount is subject to the certificate materials and the amount is limited
