Basic Concepts of Chemical Bonding

This set of flashcards covers key concepts related to chemical bonding, lattice energy, ionic charges, and Lewis structures.

What is the trend regarding ionic charge and lattice energy?

The larger the ionic charges, the greater the lattice energy.

What determines the relative lattice energy between ionic compounds?

The charge and size of the ions in the compounds.

Which has the highest lattice energy: CaO, NaF, or CsI?

CaO has the highest lattice energy due to its larger ionic charges.

What is the effect of ionic size on lattice energy?

As ionic size increases, the distance between ions increases, resulting in lower lattice energy.

What ion does strontium typically form?

Strontium forms a cation with a charge of +2.

What ion does sulfur typically form?

Sulfur forms an anion with a charge of -2.

How many valence electrons does nitrogen have?

Nitrogen has five valence electrons.

How many valence electrons does fluorine have?

Fluorine has seven valence electrons.

Which atom in the HCl molecule carries a partial negative charge?

Chlorine carries the partial negative charge due to its higher electronegativity.

What is a dipole moment?

A dipole moment is a measure of the separation of positive and negative charges in a molecule.
