Problems with Periodic Table Theory-Praxis in Chemistry Topics Teaching

open access: yesIndonesian 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]

open access: yes, 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

The Bioinorganic Periodic Table

open access: yesCHIMIA, 2019
Life depends on metals. While carbon, in terms of abundance and versatility, is considered THE element of life, the vast variety and diversity of the chemistry taking place in living organisms could not be achieved without metal ions.

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

open access: yes, 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).
