Li3N is lithium nitride, an ionic compound. Lithium, being an alkali metal, has 1 valence electron. The "3" subscript means there are 3 of them. Nitrogen is a non-metal with 5 valence electrons. This means it needs 3 more to satisfy the octet rule, which it gets from the 3 lithiums. So, nitrogen's 5 plus lithium's 1 (times 3) = a total of 8 valence electrons.

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.
What is the total number of valence electrons in oxygen?
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.
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 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.
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.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
Number of valence electrons in two hydrogen atoms?
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two 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 total valence electrons does the pf6- ion have?
The PF6⁻ ion consists of one phosphorus (P) atom and six fluorine (F) atoms. Phosphorus has 5 valence electrons, and each fluorine atom has 7 valence electrons, contributing a total of 42 electrons from the six fluorine atoms. Adding the 5 from phosphorus and accounting for the extra electron due to the negative charge, the total number of valence electrons in PF6⁻ is 48.
How do you find the number of non-valence electrons?
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
Is it true that to find the total number of electrons available for bonding in a positive ion you should add the ion charge to the total number of valence electrons of the atoms present?
No, you should subtract the ion charge from the total number of valence electrons of the neutral atom to find the total number of electrons available for bonding in a positive ion. This is because a positive ion has lost electrons compared to the neutral atom.
How many valence electrons in C6?
A carbon atom has 4 valence electrons. So, for a C6 molecule, there will be a total of 6 carbon atoms, and each carbon atom will contribute 4 valence electrons, giving a total of 24 valence electrons in the C6 molecule.
What is the total number of valence electrons in a scandium atom?
A scandium atom has 3 valence electrons.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How does the number of valence electrons change?
There is no simple answer to your question, as your question is too broad and undefined. For simple atoms, the number of valence electrons is the number of electrons in unfilled electron shells, which are then available for bonding to another atom. Oxygen with 8 total electrons has 6 paired electrons in filled electron orbitals, and 2 valence electrons in unfilled orbitals. That is why it forms bonds with 2 hydrogen molecules to form water (H2O) The number of valence electrons can change when you add or remove electrons from an atom, or in more complex atoms where filled orbitals to unfilled orbitals have the same energy and electrons can move from one to another depending on the number of other atoms it is binding with.
