Why does phosphate have 4 Oxygens?

In the phosphate ion we have a central Phosphorus atom, with five valence electrons. This is bonded to four oxygen atoms, which have six valence electrons. Five P electrons plus 4 times 6 O electrons gives 29 electrons.

Which of the following molecule has no dative bond?

CO32−

Is there any coordinate bond in phosphoric acid?

a bond in which the two electrons shared by a pair of atoms belonged originally to only one of the atoms; often represented by a small arrow pointing toward the electron receiver; e.g., nitric acid, O(OH)N→O; phosphoric Acid, (OH)3P→O.

What type of bond does phosphorus form?

covalent bond
The electron configuration of the phosphorus atom can be represented by 1s22s22p63s23p3. The outer shell arrangement therefore resembles that of nitrogen, with three half-filled orbitals each capable of forming a single covalent bond and an additional lone-pair of electrons.

Does phosphorus form double bonds?

The size of a phosphorus atom also interferes with its ability to form double bonds to other elements, such as oxygen, nitrogen, and sulfur. As a result, phosphorus tends to form compounds that contain two P-O single bonds where nitrogen would form an N=O. double bond.

What is no dative bond?

Another condition for the formation of dative bonds is that one lone pair of electrons should be found in one of atoms that is covalently bonded to another atom. The molecule which does not have dative bond is $C{O_3}^{2 – }$. We can explain the reason for this by their arrangement of atoms.

Why co32 is not a dative bond?

The carbonate ion, CO32- In the Lewis structure of CO32-, the C atom in the middle forms one double bond with an O atom and forms two single bonds with the remaining two O atoms. The two single C-O bonds include O atoms that have lone pairs that can form coordinate covalent bonds with a transition metal ion.

How many electrons are around phosphorus in phosphoric acid?

Phosphoric acid, or H3PO4 , has a total of 32 valence electrons, 5 from the phosphorus atom, 6 from each of the four oxygen atoms, and 3 from each of the hydrogen atoms.

What is the nature of the bond between phosphorus and oxygen in H3PO4?

A phosphorus oxygen bond is therefore (usually) a polar covalent bond.

Can phosphorus form 3 covalent bonds?

Phosphorous has 5 valence electrons like Nitrogen and has a good chance of forming 3 bonds with one lone pair to make an octet.

How can phosphorus make 5 bonds?

Phosphorus can have expanded octet, because it can shift it’s lone pair electrons (3s orbital electrons) to empty 3d obital during excited state and thus can form 5 bonds.

What is a dative covalent bond?

A co-ordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. For the rest of this page, we shall use the term co-ordinate bond – but if you prefer to call it a dative covalent bond, that’s not a problem!

What is donor and acceptor in dative bond?

The atom that provides electron pair is termed as Donor and the other which takes the electron pair is called Acceptor. Dative bond is represented by an arrowhead that points from donor atom to the acceptor.

Why does NH4+ form a dative bond with chlorine?

When the ammonium ion, NH4+ is created, the fourth hydrogen attached itself to a dative bond because only the nucleus of hydrogen is transferred from the chlorine to the nitrogen. The electron of the hydrogen is left behind on the chlorine to form a negatively charged chloride ion.

How many covalent bonds can phosphorus form in a stable configuration?

In general your assumption is correct, that it is possible to form only three covalent bonds to reach a stable configuration. And that will most likely be the case when phosphorus forms compounds with more electropositive elements.
