Ionisation Energy and Atomic Structure: Easy Study Notes

Atomic Structure and Ionisation Energy - A comprehensive exploration of how electrons are removed from atoms and the factors influencing this process.

  • Ionisation energy and atomic structure study notes detail the energy required to remove electrons from atoms in their gaseous state
  • The concept of factors affecting ionisation energy in atoms includes nuclear charge, atomic radius, and electron shielding
  • An explanation of successive ionisation energies demonstrates how electron arrangement affects the energy required for ionisation
  • The relationship between atomic structure and ionisation energy is fundamental to understanding chemical behavior
  • Practical examples using elements like Oxygen and Magnesium illustrate these principles

Electron Arrangement and Energy Patterns

The final page delves into the relationship between electron arrangement and ionisation energy patterns, particularly focusing on successive ionisation energies.

Definition: Successive ionisation energies show increasing values due to the changing electron-nucleus interactions.

Highlight: A dramatic increase in ionisation energy occurs when removing electrons from inner shells due to reduced shielding and stronger nuclear attraction.

Example: When removing the 7th electron from oxygen, there's a massive increase in energy required because it comes from the first shell, which experiences less shielding.

Vocabulary: Electron shielding refers to the reduction in nuclear attraction experienced by outer electrons due to inner electron shells.

Factors Affecting Ionisation Energy

This section explores the key factors that influence ionisation energy in atoms. The relationship between atomic structure and ionisation energy is explained through multiple factors.

Definition: Atomic radius refers to the distance between the nucleus and the outermost electrons.

Highlight: Three main factors affect ionisation energy:

  1. Atomic radius
  2. Nuclear charge (number of protons)
  3. Electron shielding

Example: Oxygen's successive ionisation energies demonstrate how electron arrangement affects the energy required for ionisation.

Vocabulary: Shielding occurs when inner shell electrons reduce the nuclear attraction experienced by outer electrons.

First Ionisation Energy and Basic Concepts

The first page introduces fundamental concepts of ionisation energy in atomic structure. First ionisation energy is comprehensively explained as the energy needed to remove one mole of electrons from gaseous atoms to form gaseous ions.

Definition: First ionisation energy is the energy required to remove one mole of electrons from one mole of atoms in their gaseous state to form one mole of 1+ ions.

Example: The process can be represented as Mg(g) → Mg+(g)

Highlight: The attraction between electrons and protons in the nucleus directly influences ionisation energy - stronger attraction requires more energy.

Vocabulary: Successive ionisation energies refer to the continuing process of removing additional electrons after the first one has been removed.
