The P2- anion has how many total electrons and how many valence electrons respectively? Yes. P2- has gained 2 electrons to give it a total of 17. In its valence, it has 3s2 3p5, giving it a total of 7 valence electrons.

As HCN has ten valence electrons for the Lewis structure, now there are no electrons left. The Nitrogen is having a full octet by having eight electrons in total. After that, move electrons from your outer atoms to your central atoms until they also have a full octet.

Answer and Explanation: A barium (Ba) atom has 2 valence electrons. Valence electrons are the outermost electrons in an atom, which affect how atoms might react with one...

When this is done, each oxygen atom has a total of seven valence electrons and the carbon atom has a total of six valence electrons. Because none of these atoms have an octet of valence electrons, we combine another electron on each atom to form two more bonds.

Rule 1: Count the total number of valence electrons in each atom and then add them together to get the total number for electrons in the molecule (for example, H2O has 2 x 1 + 6 = 8 valence electrons; CCl4 has 4 + 4 x 7 = 32 valence electrons).

Determine the total number of valence electrons in the molecule or ion. Each hydrogen atom (group 1) has one valence electron, carbon (group 14) has 4 valence electrons, and oxygen (group 16) has 6 valence electrons, for a total of [(2)(1) + 4 + 6] = 12 valence electrons.

Each H atom (group 1) has 1 valence electron, and the O atom (group 16) has 6 valence electrons, for a total of 8 valence electrons.

The number of valence electrons is 5 + 3×7 = 26. If you draw a trial structure in which P is the central atom and every atom has an octet, you will have used 26 electrons. This is the correct number of electrons, so the trial structure is the correct structure.

The number of valence electrons in carbon is 4 and the number of valence electrons in hydrogen is 1 and oxygen is 6. has 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom. Hence, the total number of valence electrons is 20.

As an example, let's use carbon tetrachloride, CCl4. The single carbon atom contains four valence electrons, and each of the four chlorine atoms contains seven valence electrons. Therefore, the number of valence electrons for this molecule is 4 + (4 × 7) = 32.

The number of valence electrons is the number of electrons in the outer shell, that the atom uses for bonding. Nitrogen has 5 electrons in its n=2 (outer) shell. There is a quick way of identifying the number of valence electrons - it is the same as the Group number (not for d-block elements, though).

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet.

According to some chemistry textbooks, the maximum number of valence electrons for an atom is 8, but the reason for this is not explained.

As element 34, it has 34 electrons. 2+8+18 is 28. Therefore, six electrons are on its valence shell. It all depends on shells accepting an amount of electrons.

Valence electrons are the number of electrons present in the outermost shell of an atom. Now, the last shell of chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons present in an chlorine atom.
