An atom with no valence electrons B. An atom with one valence electron C. An atom with two valence electrons D. An atom with three valence electrons I think it is B. I don't understand what valence electrons and core electrons are. Ex: Se = 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4 What makes 4s2 and 4p4 valence electrons and the rest core. 4 valence electrons. 5 valence electrons. 6 valence electrons. 7 valence electrons. 8 valence electrons. 1 valence electron. Valence electrons vary. 1 valence electron. 2 valence electrons. 3 valence electrons. 4 valence electrons.

Viewing Notes:

• CO is a clear, odorless, poisonous gas. It can be formed by combustion in oxygen poor environments and leads to a number of human deaths each year.
• In the CO Lewis structure there aren't enough valence electrons available for each atom to obtain an octet without sharing more than one pair. Therefore CO has a triple bond between the carbon and oxygen atom.
• For the CO Lewis structure there are a total of 10 valence electrons available.

Transcript: This is the CO Lewis structure: Carbon monoxide. We have 4 valence electrons for Carbon and 6 for Oxygen, for a total of 10 valence electrons. So we have a Carbon and an Oxygen atom bonded together. We'll put 2 electrons between the atoms to form a chemical bond, that's 2; and then around the outer atoms, that's 4, 6, 8, and 10.

What Is Carbon Valence Electrons

So we've used all our valence electrons. We can see Oxygen has 8 valence electrons, so it has an octet. But the Carbon only has 4 valence electrons. Let's take these two from Oxygen and share them with the Carbon. That forms a double bond. The Oxygen still has 8, but now the Carbon has 6.

Bohr Model Of Carbon Valence Electrons

So we're getting close. We'll move two more of these valence electrons to form a triple bond between the Carbon and the Oxygen. Now the Oxygen has 8, but the Carbon has 8 as well. So by now we've used all the valence electrons, all 10, and each of the atoms in the Lewis structure for CO has a full outer shell--has an octet, with 8 valence electrons.

So that's the Lewis structure for CO, carbon monoxide. This is Dr. B., and thanks for watching.
