The answer is not 6 as said here before!
The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons.
6 of them from each oxygen (O) atom.
4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each.
I hope there is some help in this.
What else can I help you with?
How many valence electrons are there in the Lewis structure of the sulfate ion so32?
There are 32 valence electrons in the Lewis structure of the sulfate ion (SO3^2-), which consists of one sulfur atom and three oxygen atoms. Sulfur contributes 6 valence electrons, and each oxygen contributes 6 valence electrons, totaling 32 valence electrons in total.
Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
How many valence electrons does the phosphate ion have?
Phosphate (PO4-3) has five valence electrons from phosphorus and six per oxygen atom for a total of 29.
The number of valence electrons in cyclopentadiene C5H6 is?
The number of valence electrons in cyclopentadiene C5H6 is 54. Carbon has 4 valence electrons and hydrogen has 1, giving a total of 30 for carbon atoms and 24 for hydrogen atoms.
How many valence electrons is OF2?
Oxygen (O) has 6 valence electrons and fluorine (F) has 7 valence electrons. In OF2, there are a total of 18 valence electrons (6 from oxygen and 2 x 7 from fluorine).
What is the total number of valence electrons in ALAS?
To find the total number of valence electrons in ALAS (which consists of aluminum (Al), sulfur (S), and four oxygen atoms), we first determine the valence electrons for each element. Aluminum has 3 valence electrons, sulfur has 6, and each oxygen atom has 6 valence electrons, totaling 24 for four oxygens. Therefore, the total number of valence electrons in ALAS is 3 (Al) + 6 (S) + 24 (O) = 33 valence electrons.
What is the number of valence electrons in CO2?
C has 4 electrons O has 6 electrons==> O2= 6*2=12 electrons CO2= 4+12 =16 electrons
What are the total numbers of valence electrons in LI2O?
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
How many valence electrons are in nitrogen monoxide?
NO2 Nitrogen has 5 valence electrons Oxygen has (6*2) =12 valence electrons therefore, the total number of valence electron =12 +5 = 17valence electrons.
How many valence electrons are in the compound Al2O3?
In the compound Al₂O₃, there are two aluminum (Al) atoms and three oxygen (O) atoms. Aluminum has 3 valence electrons, so 2 Al atoms contribute a total of 6 valence electrons. Oxygen has 6 valence electrons, so 3 O atoms contribute 18 valence electrons. Therefore, the total number of valence electrons in Al₂O₃ is 6 + 18 = 24 valence electrons.
Does O3 have an odd number of valence electrons?
No, O3 does not have an odd number of valence electrons, it has 12e- Explanation: Oxygen by itself has a total of 6 valence electrons, and since ozone (O3) is made of three Oxygen's it will be 6e- X 3 which yields 18e- . But since these three elements are (covalent) bonded together with a single and double bond you need to subtract 2e- and 4e- which will give us the final answer of 12e- You can now conclude that it has an even number of valence electrons.
What is the total number of valence electrons in the Lewis structure of NO2-?
In the Lewis structure of the nitrite ion (NO2-), nitrogen contributes 5 valence electrons, each oxygen contributes 6 valence electrons, and the extra negative charge adds 1 more electron. Therefore, the total number of valence electrons is 5 + (2 × 6) + 1 = 18 valence electrons.
What the total number of valence e OF2?
The total number of valence electrons in OF2 is 18. This is calculated by adding the number of valence electrons for each atom (O has 6 and F has 7) and considering that there are two fluorine atoms linked to one oxygen atom in the molecule.
How many valence electrons does H2SO4?
Each H has 1. Each O has 6 and the S has 6. That's a total of 32 valence electrons.
What is the total number of electrons present in a Oxygen?
there are 8 electrons in an oxygen atom, equal to the number of protons. there are 6 valence electrons though, give or take because they constantly switch
