Metallic bonds are one of the 3 main types of intermolecular forces, along with ionic bonds and covalent bonds. Metals are shiny, malleable, ductile, and good conductors of heat and electricity. Is there a reason, chemically, for these characteristics of metal?
In this video we explain the connection between the nature of metallic bonds and these typical features.

1:23 Metals are shiny
1:48 Metals are good conductors of heat
2:04 Metals are good conductors of electricity
2:20 Metals are malleable
3:01 Metals are ductile
3:43 Metals have recognizable crystal structures
3:53 Which metal is liquid at room temperature? Any others?
Correction:
1:33 This is a description of light emission, not reflection. Reflection is a better explanation for the shininess of metals.
Here's a discussion about these phenomena: [ Ссылка ]/Optical_Properties/Metallic_Reflection#:~:text=Metals%20are%20known%20for%20having,is%20also%20low%20for%20metals.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. Kimberly co-founded Socratica Studios.
