6th - Covalent Formulas, Naming, and Electronegativity

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

Define electronegativity.

Back

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

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

How do you determine the molecular shape of a molecule?

Back

The molecular shape 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 formula for sulfur hexafluoride?

Back

SF6

Front

Which of the following is a diatomic molecule: H2, O3, CH4, NH3?

Back

H2 is a diatomic molecule.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons from one atom to another, while covalent compounds are formed by the sharing of electrons.

Front

What is the correct name for the compound N2O4?

Back

Dinitrogen tetroxide.

Front

How do you name a covalent compound?

Back

Covalent compounds are named using prefixes to indicate the number of atoms of each element present.

Front

What is the shape of methane (CH4)?

Back

Methane (CH4) has a tetrahedral shape.
