What describes the molecular geometry of a molecule with four electron groups with only bonded pairs?
trigonal planar
What is the difference between the arrangement of electron pairs and the shape of the molecules?
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What is the role of unshared electron pairs in predicting molecular geometries?
Lone electron pairs give the geometry a triangular base.
How do you determine the molecular geometry of a molecule?
The molecular geometry of a molecule can be determined using the VSEPR theory. VSEPR (Valence Shell Electron Pair Repulsion) Theory: The basic premise of this simple theory is that electron pairs (bonding and nonbonding) repel one another; so the electron pairs will adopt a geometry about an atom that minimizes these repulsions. Use the method below to determine the molecular geometry about an atom. Write the Lewis dot structure for the molecule. Count the number of things (atoms, groups of atoms, and lone pairs of electrons) that are directly attached to the central atom (the atom of interest) to determine the overall (electronic) geometry of the molecule. Now ignore the lone pairs of electrons to get the molecular geometry of the molecule. The molecular geometry describes the arrangement of the atoms only and not the lone pairs of electrons. If there are no lone pairs in the molecule, then the overall geometry and the molecular geometry are the same. If the overall geometry is tetrahedral, then there are three possibilities for the molecular geometry; if it is trigonal planar, there are two possibilities; and if it is linear, the molecular geometry must also be linear. The diagram below illustrates the relationship between overall (electronic) and molecular geometries. To view the geometry in greater detail, simply click on that geometry in the graphic below. Although there are many, many different geometries that molecules adopt, we are only concerned with the five shown below.
What is a molecule bonding?
Just as the valence electrons of atoms occupy atomic orbitals (AO), the shared electron pairs of covalently bonded atoms may be thought of as occupying molecular orbitals (MO).

Can more than one pair of electrons be shared?
Absolutely more than one electron pairs can be shared like in oxygen molecule double covalent bond exists as there is sharing of two electron pairs.Similarly triple bonding exists in nitrogen molecule.
What are the three of the many possible shapes of molecules?
Without given a specific molecule there is not any way to determine the shape. Beryllium chloride consists of beryllium in the middle and a chlorine on each side, and is in the shape of a straight line.
What type of electron pairs make a molecule a good donor?
the lone pair on electron like nh3 make molecule good donor.
Is covalent molecular?
A covalent bond is one in which atoms within a molecule share pairs of electrons (hence the term covalent or "mutual electron state"). It is not clear to me what is meant by "molecular" in your question, but the bond is intramolecular(or inside the molecule). A covalent bond is a type of molecular bond, if that is the question.
What is the role of unshared electron pairs in predicting molecular geometries?
Lone electron pairs give the geometry a triangular base.
How many electron pairs are shared between carbon atoms in a molecule that has the formula C2H4?
in C2H6 only one pair of electrons are shared between the carbon atoms.

Which configurations would form a bent molecule?
