A molecule having four total electron groups around the central atom has three bonding electron groups and one nonbonding electron group what is its molecular structure

trigonal pyramidal

How is the oxidation state of a transition metal determined from the chemical formula

The subscript of the second ion identifies the oxidation state of the transition metal

What would cause the shape of a molecule to be tetrahedral

Four atoms bound to a central atom with no lone pairs

Which of the following configurations would form a bent molecule

a molecule with two bound atoms and one lone electron pair -apex

What shape would a molecule with two bound groups and two lone pairs have

The correct answer is: Bent.

What best describes a bond formed between two unlike atoms

The type of bond is determined by the difference in electrongativity of atoms

How does the shape of a molecule affect the polarity of the molecule

C.A molecule that has a symmetrical shape will be a nonpolar molecule.

What effect does a lone electron pair have on molecular shape

The lone pair pushes bonding electron pairs away.

What are repelled in the VSEPR theory

Electron pairs

How many total electrons can the p orbitals hold

Six in p orbital, in each sublevel of p (px, py, pz) there are two electrons at max.

What is a consequence of electron-pair repulsion around an atom

The atoms sharing the electron pairs will spread out around the central atom. Apex

How is the electronagativity trend related to the first ionization energy trend

Electronegativity and first ionization energy both increase as you move up the periodic table

What type of bonding around a central would result in a trigonal planar molecule -apex

3 atoms around a central atom with no lone pairs.

How does a lone pair contribute to the molecular shape

The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.

What bond has a very strong dipole dipole force

a hydrogen bond
