research paper on chemical bonding

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for future research and instruction. To this end ...

Chemical bonding is a key concept in chemistry. It is also a topic ar ea where understanding is. developed through div erse models - which are in turn built upon a range of physical principles ...

1. Introduction. Bonding is what separates chemistry from physics. If the understanding of atoms and their component particles belongs primarily to the realm of physics, then chemistry is concerned with the aggregation of atoms into chemical entities held together by bonds.If science is a language, and atoms are the letters, bonding is the mechanism by which the letters are combined into words.

Following the paper by Levy Nahum et al. (2007) (see also: Kronik et al., 2008), which developed "a new teaching approach (the 'bottom up' approach) for the chemical bonding concept aligned with current scientific and pedagogical knowledge", there has been a revival of interest in teaching and learning of the topic of chemical bonding.

1. Introduction. Covalent chemical bonding is undoubtedly a central concept in Chemistry. While bond formation is arguably the most fundamental chemical process, its physical origin is still the subject of debate, even today when accurate quantitative molecular electronic structure calculations of ever-increasing accuracy and complexity have become widely available.

Chemical bonding is an important topic which is difficult to teach well, especially for novices. This study set out to support preservice teacher educators by developing a framework for ...

A conceptual framework for a new teaching approach was constructed with lead-chemistry teachers, science (chemistry) educators, and research chemists. We suggest that chemical bonding should be taught based on elemental principles and by using the idea of a continuum of bond strengths.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications. ... Chemical bonds are treated as n ...

In their review of "Research on the Teaching and Learning of Chemical Bonding", Hunter et al. (2022) annotate that most of the reviewed studies interpret students' alternative conceptions as ...

Chemical bonding is a fundamental but complex topic, which has traditionally been associated with learning difficulties, misunderstandings, and misconceptions. This paper reviews some previous studies, concerning students' conceptual difficulties and reports the findings from a research study with Greek stud

The calculation of the energy of H 2 using the classical approach yields only a shallow energy minimum with a bond energy of ∼10 % of the correct value. Figure 1 shows a re-drawing of the original curve of Heitler and London where the classical energy is denoted as E 11.The energy curves E α and E β come from the quantum theoretical approach, which gives two solutions for equation 9 ...

Coinciding with the centennial commemoration of the electron-pair bond proposed by Gilbert Newton Lewis in 1916 1, a considerable number of research papers 2,3, perspective articles 4,5,6 and ...

Chemical bonding refers to the attraction between atoms and can come in several different types with varying strength. It allows the formation of substances with more than one atomic component and ...

A summary of diagnostic studies on chemical bonding The conceptual difficulties that students encounter when studying the topic of chemical bonding lead many of them to resort to rote memorizing and the formation of misconceptions (e.g. Levy Nahum, Mamlok-Naaman, Hofstein, & Krajcik, 2007), many of which prove resistant to instruction.

The Art of the Chemical Bond. Chemical bonding enables scientists to take the 100-plus elements of the periodic table and combine them in myriad ways to form chemical compounds and materials. The success rate is pretty good, as more than 120 million chemical substances are currently registered by CAS, a division of the American Chemical Society.

It was found that while the two groups demonstrated similar performance for many bonding concepts, the treatment group did show superior knowledge with respect to a number of issues, such as the role of electrostatic interactions, electronegativity, and bond polarity. Chemical bonding is a fundamental but complex topic, which has traditionally been associated with learning difficulties ...

The present paper presents a detailed thematic review of chemical bonding studies. To achieve this, a matrix is developed to summarize and present the findings by focusing on insights derived from the related studies. ... implications for curriculum development and suggestions for future research. The general knowledge claims investigated in ...

Educ. Res. Pract., 19, 1253-1269.

The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. ...
