Bonding and Ionic Compounds

A set of flashcards covering key concepts related to atomic bonding, ionic compounds, and their properties, naming conventions, and stability principles.

Why do atoms want a full shell of electrons?

Atoms seek a full shell of electrons, typically 8 (except hydrogen, which needs 2), to achieve stability.

What is a covalent bond?

A bond formed when non-metal atoms share electrons.

What is an anion?

A negatively charged ion that gains electrons.

What characterizes ionic compounds in terms of structure?

Ionic compounds form a 3D lattice structure where positive and negative ions are attracted to each other.

What are common properties of ionic compounds?

Ionic compounds typically have high melting and boiling points, are very hard, and do not conduct electricity in solid form.

How are ionic compounds named?

The name of the metal remains the same, while the non-metal name ends in -ide.

What prefixes indicate the number of atoms in covalent compounds?

Prefixes such as mono- (1), di- (2), tri- (3), tetra- (4), penta- (5), hexa- (6), hepta- (7), and octa- (8) are used.

What happens when naming covalent compounds?

The prefix indicates the number of each element; the second element's name ends in -ide.

What is the process called when charges in ionic compounds are balanced?

The 'Drop and Swap' method is used to balance the charges between cations and anions.

What is the significance of valence electrons in bonding?

Valence electrons are used to form bonds and determine the chemical properties of elements.
