Journal Entry:
What gives rise to the majority of the properties of a metallic solid? Explain one such property.
Learning Intentions
We will learn about structure and properties of metallic solids.
We will learn the different types of metal solids and how they can be distinguished from each other.
We will be how macroscale properties of various metals relate to microscopic structure.
Closing Task:
You can build a model of one of the three types of metallic solids and be able to explain the structural components of your model and how the structure relates to properties.
Content Standards being covered:
Students can predict the type of bonding present between two atoms in a binary compound based on position in the periodic table and the electronegativity of the elements. (LO 2.17)
Metallic bonding describes an array of positively
charged metal cores surrounded by a sea of mobile valence electrons. (EK 2.C.3)
Students are able to explain how a
bonding model involving delocalized electrons is consistent with macroscopic
properties of metals and the shell model of the atom (LO 2.20)
Metallic solids are good conductors of heat and
electricity, have a wide range of melting points, and are shiny, malleable,
ductile and readily alloyed. (EK 2.D.2)
Students can create a representation of
a metallic solid that show essential characteristics of the structure and
interactions present in the substance.
