Why is the number of electrons provided by a CO 2 10

Generally speaking, Co ligands are coordinated by C, and after coordination at one end of C, it is impossible for O atoms to participate in coordination from a spatial point of view.

And in general, the neutral O atom is not a good ligand, and often the cases where O participates in coordination are in the form of O2-.

As far as the specific CO molecule is concerned, the formation of this molecule is due to the coordination of a lone pair of electrons of O to the empty orbital of the C atom, similar to the form of a triple bond, so C is equivalent to getting more than the part of the electrons that do not belong to it, so the C atom will have a form of negative charge, because the electronegativity of C itself is relatively small, it will tend to disperse this negative charge, so the C of CO has a strong coordination, while the O atom has no coordination.

You can compare the structure of CO to N2, which are isoelectrons.

A ligand that provides multiple coordination bonds is called a chelating ligand, which tends to be more than 3 atoms, and this diatomic ligand of CO generally only donates 2 electrons.

The C electron is 6 and the O electron is 8, so the Co electron is 14 and the CO2 electron is 22

Let the masses be 1 gram, then the ratio of the number of electrons of the same mass of Co and Co2 is:

Co unpaired electron number [ar]3d8 4s2.

At the time of the formation of co, the two pairs of electrons in the two p orbitals of oxygen enter the orbitals of the two unpaired electrons of carbon, respectively, to form two pairs of shared electron pairs.

And the spin direction is reversed, and the remaining pair of patterns on the 2p of oxygen is a lone pair of electrons.

Entering the empty orbital on the 2p of carbon, a coordination bond is formed.

Thus forming a carbon-oxygen triple bond.

Layout rulesEach electric state cherry blossom layer.

The maximum number of electrons that can be accommodated is 2n2 (n is the number of the electron shell). The number of electrons in the outermost shell does not exceed 8 (no more than 2 when the k-layer is the outermost). The number of electrons in the subouter shell does not exceed 18, and the number of electrons in the penultimate shell does not exceed 32.

Electrons outside the nucleus are always arranged in the lowest energy electron shell first, and then from the inside out, the L layer is arranged before the M layer. The above four laws are interrelated and cannot be understood in isolation.

1. Number of atoms:

With the same number of atoms, both are 2mol, which is 2 atoms. co, 1 each for c and o, for a total of 2

2. Number of electrons:

c（6 ) o(8) -co(14)

n(7)+ n(7) -n2(14)

Both are isoelectrons and both have 14 electrons.

28 and 30 are the relative molecular masses of CO and NO, respectively.

Not their total number of protons, the total number of protons and the total number of electrons are equal.

Relative molecular mass is the relative atomic mass.

Sum, relative atomic mass = number of protons.

Number of neutrons. c: 6 protons and 6 neutrons, 6 relative atomic fiber 6 + 6 = 12o:

The number of protons is 8, the number of neutrons is 8, and the relative atomic mass is 8+8=16n: the total number of electrons for the number of protons is 7, the number of neutrons is 7, and the total number of electrons for the relative atomic mass 7+7=14co is equal to the total number of protons, 6+8=14, and the relative molecular mass is 12+16=30

Not all electrons are half the relative mass of the atom, but the three elements are just equal in number of protons and neutrons.

The number of electrons in a CO molecule is: 6+8 14

The number of electrons in a CO molecule is: 6+8x2 22

The ratio of the number of electrons to CO2 of the same amount of matter = 14:22 7:11

The number of electrons is to look at the number of elements c 6 electrons o 8 electrons of element 8.

The number of electrons in Co is 6+8=14

The number of electrons in CO2 is 6+8*2=22

Answer: 16:22=8:11

There are 6 electrons outside the carbon nucleus and 8 electrons outside the oxygen nucleus.

So 14:22==7:11

1 CO2 contains 6+8 = 22 electrons.

Contains 22 electrons, i.e. the number of electrons is about 11na.

C has 6 electrons and O has 8 electrons, so CO has 8+6=14 electrons in a molecule.

Co: 6 electrons in 1 c, 8 electrons in 1 o, a total of 14 electrons.

CO2: 1 electron in 6 C and 2 electrons in 16 O, for a total of 22 electrons.
