Chemistry: Bonding

Front

What is a Lewis dot structure?

Back

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

How do you determine the formula for a compound formed between two elements using the criss-cross method?

Back

The criss-cross method involves taking the charge of one ion and using it as the subscript for the other ion, and vice versa, to balance the overall charge of the compound.

What type of ions do metals typically form?

Back

Metals typically form positive ions.

Front

What is electronegativity?

Back

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

Front

What is the electronegativity difference between hydrogen and oxygen in water (H2O)?

Back

The electronegativity difference is 1.24.

Front

What is the significance of a positive ion?

Back

A positive ion, or cation, is formed when an atom loses one or more electrons, resulting in a net positive charge.

Front

What is the significance of a negative ion?

Back

A negative ion, or anion, is formed when an atom gains one or more electrons, resulting in a net negative charge.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons, achieving a stable electron configuration.
