The discussion centers around the question of whether an atom can exist without electrons, exploring theoretical and practical implications in chemistry and physics. Participants examine various examples, definitions, and the nature of ions and nuclei.
Participants express differing views on the definition of an atom and whether certain charged species can be classified as atoms. No consensus is reached regarding the existence of atoms without electrons, and multiple competing perspectives remain.
Definitions of atoms and ions are debated, with some participants emphasizing the importance of charge neutrality in the definition of an atom. The discussion also highlights the instability of certain ionic states and the conditions under which they may be produced.
This discussion may be of interest to students and professionals in chemistry and physics, particularly those exploring atomic structure, ionization, and the behavior of charged particles in various states of matter.
chem_tr said:ZapperZ, I am doubtful about this. When you write the alpha particle, ^{4}_{2}He, you'll see that two electrons are present as this compound is neutral and monoatomic. You'd be correct if this compound were a 2+ ion. Or is there something I don't know?
