How many extra electrons are in the Lewis structure of the phosphate ion PO 4 3?

∙ 12y ago
The P04 3- ion has zero unshared pairs on the phosphorous atom and a total of 11 unshared pairs on the four oxygen atoms. The lewis structure can be represented as four different resonance structures, because an extra bonding pair is shared between the four oxygen atoms

∙ 12y agoIt contains 3 extra electrons because it has a charge of -3 which means there must be 3 more electrons than usual to make the atom an ion and not be at a ground state.

What is the valence number for calcium phosphate?
Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
What is the correct Lewis electron-dot diagram for an atom of sulfur- 33?
..:O:.. l ..:O-S-O:" l ":O:" (SO4)2- 32 total electrons: 6 per atom plus 2grrr it wont get the spaces right. its 4 oxygen around a sulfur, all single bonds. each oxygen has 6 extra electrons around it
Explain why metals react with non-metals.?
The simplest explanation is that metals have valence electrons to give away, and non metals need extra electrons to complete their valence shell.
What is the deficiency of sodium?
sodium does not have a deficiency of electrons but has an extra electron in its outermost shell,which it loses to form an ionic bonds.
When an atom of magnesium forms an ionic bond with an atom of oxygen which will gain electrons?
Magnesium has a charge of 2+ and oxygen 2- Magnesium will lose the two "extra electrons" in its valence shell when creating an ionic bond with oxygen. The oxygen will gain these two electrons.
Why does F3- not form a Lewis structure?
F3- does not form a Lewis structure because F (Fluorine) has 7 valance electrons. F3 totals 21 valance electrons +1 for the - charge for a total of 22. However when you attempt to bond 3 F atoms together in a Lewis structure there is only space for 20 valance electrons. This is not a problem for atoms like Br or I because they can fit those extra electrons in the near by d orbital. Fluorine being a period 2 element does not have a d orbital and can not form a F3- Lewis structure. -JCS

What is the Lewis dot structure for I3 plus?
I -> 7e- O(3x) -> 3(6e-) = 18e- Since its an IO3- it has an extra electron Total electrons = 18e- + 7e- +1e- = 26e- I is the Central Atom Each O has a single bond with 6 valance electrons and I and 2 Structure : Trigonal Pyramidal

What is the term for semiconductors that contains extra electrons?
N-type semiconductor contains extra electrons.
In the Lewis structure for a molecule of methyl chloride (CH3Cl) how many lone pairs of electrons does chlorine have when it is bonded to carbon?
Two lone pair on the central selenium and three lone pairs on each chlorine. So total of eight lone pairs.
What is the term for a semi conductor that contains extra electrons?
N-type semiconductor contains extra electrons.
Why is steel a conductor?
because it stole a conductor, it is conductive because the steel has extra electrons and when extra electrons get introduced to the steel, it releases its electrons and takes in the new electrons and this happens in a continually
What has the author Lewis Hastings written?
Lewis Hastings has written: 'Dragons are extra'
How do the ATP and ADP molecules look different?
An ATP molecule has an extra phosphate group compared to an ADP molecule. This is because ATP has 3 phosphate groups as where ADP only has two phosphate groups.
Do an isotope have extra electrons or protons?
protons
