Metallic bond
Metal atoms form a crystal lattice of positive ions held together by their free valence electrons; in general, more bonding electrons give a stronger bond (not a rule for every metal: the chapter's melting-point table breaks it at Mn and Cu).
The idea, in English
Metal atoms form a crystal lattice of positive ions held together by their free valence electrons; in general, more bonding electrons give a stronger bond (not a rule for every metal: the chapter's melting-point table breaks it at Mn and Cu). Explains conductivity and why layers can slide (malleability).
Explain in Egyptian Arabic
الـ metal atoms بتكوّن crystal lattice من positive ions، ماسكها في بعض الـ free valence electrons بتاعتها. وبشكل عام، bonding electrons أكتر بتدي bond أقوى (لكن دي مش قاعدة لكل الـ metals). والـ bond ده بيفسّر الـ conductivity، وليه الطبقات تقدر تتزحلق على بعض (الـ malleability).
