Chapter 6, Problem 6.90PAE

Interpretation Introduction

Interpretation:

The elements that the ionization gauge will be able to detect if the electron collection grid voltage is set to 1200 kJ/mol should be identified. In addition, an explanation must be provided explaining how the ionization gauge can be suitably modified to detect sodium and magnesium atoms.

Concept Introduction:

• The energy required to remove one (or more electrons) from an atom to form a positively charged ion (cation) is called ionization energy
• The valence electron is the most loosely bound electron in an atom which requires relatively lower energy for removal. This is the first ionization energy of an atom.
• Subsequent removal of inner electrons requires higher energy
