How many lone pairs can the Bent Shape have?

1 (AX2E) or 2 (AX2E2)

I believe that it can either be one lone pair or two lone pairs that make a linear shape. Because a molecule with three lone pairs and two atoms would give you a linear geometry.

It can have one lone pair or two lone pairs. This is a link to an image showing the two different molecular shapes: http://intro.chem.okstate.edu/1314F97/C ... PMain.html

If a molecular had 2 bonding groups and 1 lone pair, or 2 bonding groups and 2 lone pairs, the molecular shape would be bent.

One or two, depending on it's VSEPR formula. It can be either AX2E or AX2E2.

one or two, which also decide the bond angle.

The bent shape can have 1 lone pair when its electron geometry is trigonal planar and 2 lone pairs when its electron geometry is tetrahedral.

Remember with the bent shape and how it is angular, you need to know that there is a different angle degree for the different VESPER formula. AX2E2, will have an angle that is less than 120 degrees. But when it is AX2E3 the bond angle is less than 109.5 degrees.

Yea if the formula is AX2E then the angles are similar to a trigonal planar molecule (<120) but if the formula is AX2E2 then the bond angles are similar to a tetrahedral molecule (<109.5)

If the molecule has 3 regions of electron density, but one is a lone pair, then it can be bent (< 120 degrees). However, if the molecule has 4 regions of electron density, and two of them are lone pairs, then it can also be bent (< 109.5 degrees).

A bent shape will have only one or two lone pairs, with VESPR functions AX2E or AX2E2.

A bent shape can have up to one or two lone pairs around the central atom.

If their is one lone pair on the central atom when connected to two adjoining atoms, you will have a bent structure. Without the lone pair, the angle would be 180 degrees, or completely linear. However, the one lone pair pushes down on the outside two atoms creating a bond of less than 180

Bent can have either one lone pair: which makes an electron geometry of trigonal planar because three things around the central atom and therefore a molecular geometry of bent. it can also have two lone pairs: which makes an electron geometry of tetrahedral because 4 things around the central atom and therefore a molecular shape of bent.

It can have 1 or 2 lone pairs. If you look at the shape of a trigonal planar molecule, it looks like the shape of a bent molecule. The difference is that instead of 3 atoms around the central atom, there are 2 atoms and a lone pair around the central atom, making it have a bent shape. The same concept applies to a tetrahedral molecule -- instead of 4 atoms around the central atom, there are 2 atoms and 2 lone pairs.

Bent shape can have one or two lone pairs. One lone pair turns a trigonal planar into a bent molecule and two lone pairs turn a tetrahedral into a bent molecule.
