In PCl3 there are three bonds to the central atom (P) and one lone pair..
This can be worked out as follows. P has 5 valence electrons, shares three electrons with the chorine atoms (1 each) leaving 2 electrons on the P as a lone pair. In VSEPR theory this is an AX3E compound like ammonia.

How do you find lone pairs?
one can find the bond pairs by finding the oxidation state on the central atom
What is the Lewis structure for AX1E0?
The Lewis structure for AX1E0 is linear, with one central atom (A) and no lone pairs or unshared electron pairs (E). This means that A is bonded to one other atom (X) with a single bond.
What causes an atom to form a hydrogen bond?
A hydrogen bond is a weak bond formed between two molecules or atoms. It is caused by an atom of hydrogen being attracted to spare electron pairs on a neighbouring atom.
What is the atom bonded to central atom and lone pair on central atom of C2H2?
The question is not answerable. There is NO central atom in C2H2 (ethyn) and there's NO lone pair. All electrons are covalently shared in pairs: three pairs between C and C, one single pair in each C and H bond.
In carbon dioxide each oxygen atom shares four electrons with the carbon atoms what is this type of bond called?
The bond where each oxygen atom shares four electrons with the carbon atom is called a double bond. In a double bond, two pairs of electrons are shared between two atoms.
If two atoms are bonded to a central atom with no lone pairs how will they be placed?
The two atoms will be placed on opposite sides of the central atom, creating a linear molecular geometry. This arrangement maximizes the bond angles and minimizes repulsion between the bonding pairs.
How many bond pairs does BCl3 have?
BCl3 has 3 bond pairs. Each chlorine atom forms a single covalent bond with the central boron atom.
What is the bond of AB2E2?
The bond of AB2E2 is a bent molecular geometry. The central atom is bonded to two other atoms and has two lone pairs of electrons. This results in a bent shape due to the lone pairs repelling the bonded atoms.
The central atom in the iodite ion IO2- is surrounded by?
The central atom in the iodite ion IO2- is surrounded by three oxygen atoms.
How do you find lone pairs?
one can find the bond pairs by finding the oxidation state on the central atom
What is the molecular shape of XeF6?
The molecular shape of XeF6 is octahedral. This shape occurs when there are six bond pairs and no lone pairs around the central xenon atom. The six fluorine atoms are positioned at the corners of an octahedron around the xenon atom.
Which molecular geometry is characterized by 109.5 degree bond angles?
The molecular geometry characterized by 109.5 degree bond angles is tetrahedral. This geometry occurs when a central atom is bonded to four surrounding atoms with no lone pairs on the central atom. An example of a molecule with this geometry is methane (CH4).
What is the Lewis structure for AX1E0?
The Lewis structure for AX1E0 is linear, with one central atom (A) and no lone pairs or unshared electron pairs (E). This means that A is bonded to one other atom (X) with a single bond.
What is the Lewis structure for germanium iodide?
The Lewis structure for germanium iodide (GeI4) has germanium (Ge) as the central atom surrounded by four iodine (I) atoms. Each iodine atom is bonded to the germanium atom with a single bond, and there are no lone pairs on the germanium atom.
What causes an atom to form a hydrogen bond?
A hydrogen bond is a weak bond formed between two molecules or atoms. It is caused by an atom of hydrogen being attracted to spare electron pairs on a neighbouring atom.
Why is Hydrogen and Fluorine cannot be central atoms in Lewis dot structurs?
Hydrogen cannot be a central atom in a Lewis structure because it can only form one bond due to its single electron. Fluorine cannot be a central atom because it is highly electronegative and prefers to be on the outside of a molecule, typically forming one bond.
What factors affect bond angle of a molecule?
The bond angle of a molecule is affected by the repulsion between electron pairs around the central atom. Factors such as the number of electron pairs and the presence of lone pairs can influence the bond angle. Additionally, atomic size and electronegativity of the atoms involved can also affect bond angles.
