Chapter 5a - Chemical Bonding

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does Oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the purpose of bond formation?

Back

Bonds form to fill the valence shell of electrons for the elements involved, achieving stability.

Front

What is the molecular geometry of BF3?

Back

The molecular geometry of BF3 is trigonal planar.

Front

What type of bond is characterized by a sea of free-moving electrons?

Back

Metallic bond.

Front

What is a Lewis electron-dot structure?

Back

A Lewis electron-dot structure is a diagram that represents the valence electrons of an atom as dots around the element's symbol.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

The shape of a molecule with four bonding pairs and no lone pairs is tetrahedral.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.
