  1. Start studying Monatomic Ion List. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
  2. Ions from the region of interest pass through the hole in the FIM screen and into the mass spectrometer. Field evaporation typically produces singly or doubly charged monatomic ions, though higher charge states are seen for refractory elements, and nonmetallic elements can generate cluster ions. Individual ions are identified by measuring the.

In this section we shall assign electrons to orbitals and come up with some rules to determine the ground state electron configuration of atoms of the different elements. The ground state configuration is the lowest energy configuration, and the ground state electron configuration affects the behavior of atoms and results in the elemental structure of the periodic table. For example, all the alkali metals have 'isoelectronic' valence shell electron configurations. That means their outer shells have similar numbers of electrons in similar orbitals, which for the alkali metals have a ns1 electron configuration, where n is the outer (valence) shell. Because of this they behave similarly, and for example, can easily lose the outer electron and form a cation of charge [+1].

Monatomic Ionic Compounds

Monatomic Ion (aka 'Charged Atom' aka 'Atomic Ion') A single atom with an unequal number of protons and electrons. In other words, it is an ion consisting of a single atom. Atoms with a Net Negative Charge (aka anion, aka negative ion) An atom with more electrons than protons.

Monatomic Ion Definition

It should be emphasized that the electron configurations we are describing are the ground state or lowest energy state configuration. In real systems atoms contain energy and electrons can exist in excited states, so you will have populations of atoms in different states, and these atoms will be perpetually changing states as they exchange energy with each other and the surrounding. At higher temperatures there will be more atoms in excited states. These atoms will relax back to the ground state, by either transferring thermal energy to other atoms or giving off a photon (radiative relaxation), and it was these radiative process that resulted in the atomic line spectra of the last Chapter.
