2nd - Covalent Formulas, Naming, and Electronegativity

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the general formula for covalent compounds?

Back

Covalent compounds do not have a specific formula; they are represented by molecular formulas that indicate the number of each type of atom present.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

How do you determine the shape of a molecule?

Back

The shape of a molecule can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory, which states that electron pairs around a central atom will arrange themselves to minimize repulsion.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

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

Back

The shape is tetrahedral.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

The shape is trigonal pyramidal.

What is the chemical formula for water?

Back

The chemical formula for water is H₂O.

Front

What is the chemical formula for carbon dioxide?

Back

The chemical formula for carbon dioxide is CO₂.

Front

What is the chemical formula for disulfur hexoxide?
