Chemical Bonding Overview

Vocabulary flashcards based on the concepts of chemical bonding, including definitions of ionic and covalent bonding, the octet rule, and related terms.

Ionic Bonding

Involves a transfer of electrons where one element loses electrons and the other gains electrons.

Covalent Bonding

Involves a sharing of electrons between atoms to reach a stable electron configuration.

Octet Rule

Atoms will gain or lose enough electrons to become isoelectronic with a noble gas.

Valence Electrons

Electrons in the outermost shell of an atom that determine its chemical properties.

Electron Dot Structures

A way to show the number of valence electrons in an atom, represented by dots around the symbol.

Formula Unit

The lowest whole number ratio of ions in an ionic compound.

Ionic Compound

A compound that consists of crystals formed from the attraction between positively and negatively charged ions.

Melting Points of Ionic Compounds

Ionic compounds have high melting points due to strong electrostatic forces between ions.

Conductivity of Ionic Compounds

Ionic compounds conduct electricity when melted or dissolved in water.

Group Number and Valence Electrons

The number of valence electrons can be determined by the group the elements are in, specifically from the s and p blocks.
