The authors, who have more than two decades of combined experience teaching an atoms-first course, have gone beyond reorganizing the topics. They emphasize the particulate nature of matter throughout the book in
Thus, as summarized in Figure 2, we assumed that novice students would have a macroscopic continuous view of matter; as they progress in their studies, they would understand atoms as particles, followed by the understanding that these particles have protons, neutrons, electrons. Finally, they ...

This could hint that chemists have a liking towards molecules that feature neutral nitrogen atoms. We however stress that the magnitude of these correlations is, in our opinion, insufficient to make any strong claims. Nevertheless, for completeness, an extensive list of all of the properties ...
This analogy with organometallic complexes and the electronic structure of SAAs akin to gas phase atoms17,18have motivated us to consider an MO approach to rationalize the binding of adsorbates on SAAs (Fig.2). Based on the symmetry point groupC∞νof the metal–adsorbate pair, we can constru...
The molecules possessing fluorine atoms (PTZ 2–4) exhibit the emission maximum red-shifted with the decreas- ing number of fluorine atoms indicating the presence of two and one acceptor groups (-CF3) lessens the shift to longer wavelengths. This phenomenon caused the reduction of the optical ...
At NASA’s Cold Atom Lab facility aboard the International Space Station, an international team of scientists produced a quantum gas containing two types of atoms for the first time in space. The achievement, outlined in a new study published in Nature, marks another step toward bringing quantum...
(using cabbage as an indicator) into an inquiry, and subsequently, we use an historical model to propose a sequence of activities based on the modeling cycle of Couso and Garrido-Espeja for lower secondary school. Finally, we identify some implications for a model-focused teaching approach for ...

In this work, we provide an overview of commonly used chemical transformations for the syntheses of PET tracers in all aspects of radiochemistry, thereby highlighting recent breakthrough discoveries and contemporary challenges in the field. We discuss the use of biologicals for PET imaging and high...
