Problems with Periodic Table Theory-Praxis in Chemistry Topics Teaching

Indonesian Journal of Science and Mathematics Education, 2023
The two main chemical concepts that are the subject of this investigation are chemical bonds and related reactions. This research examines how the periodic table concept can help teachers improve science teaching. To help students understand the contents

The generalized Lindemann melting coefficient [PDF]

, 2020
Lindemann developed the melting temperature theory over 100 years ago, known as the Lindemann criterion. Its main assumption is that melting occurs when the root-mean-square vibration amplitude of ions and atoms in crystals exceeds a critical fraction, h

Periodic Unit and its Effect on Improving Academic Performance of Students in Anatomy- A Pilot Study [PDF]

International Journal of Anatomy Radiology and Surgery, 2021
Introduction: Anatomy is one of the basic sciences of medicine. Optimal anatomical knowledge is essential for competent future doctors. Assessments in medical education not only help the students but also, the teachers to address the critical areas of

Who is a theorist? [PDF]

, 2011
This article carefully analyzes a recent paper by Weisberg in which it is claimed that when Mendeleev discovered the periodic table he was not working as a modeler but instead as a theorist.

From the Mendeleev periodic table to particle physics and back to the periodic table [PDF]

, 2006
We briefly describe in this paper the passage from Mendeleev's chemistry (1869) to atomic physics (in the 1900's), nuclear physics (in the 1932's) and particle physics (from 1953 to 2006).

Understanding Periodic and Non-periodic Chemistry in Periodic Tables [PDF]

Frontiers in Chemistry, 2021
The chemical elements are the “conserved principles” or “kernels” of chemistry that are retained when substances are altered. Comprehensive overviews of the chemistry of the elements and their compounds are needed in chemical science. To this end, a graphical display of the chemical properties of the elements, in the form of a Periodic Table, is the ...
