Name two properties shared by metals?
they are oxygen and water
What two properties are explainedby the pool-of-shared-electrons for metals?
malleability< conductivity
What is a physical property shared by all metalloids?
They are all solids. They have properties of metals and non metals.
What physical properties are shared by most non-metals?
They have high ionization energy and high electronegativity.
What chemical properties are shared by most metals?
Metals conduct electricity. Metals ionise [lose one or more electrons] to form positively charged ions - cations.

Which properties are explained by the pool-of-shared-electrons model for metals?
Conductivity (of both heat and electricity) and malleability.
What are shared properties?
Properties that are shared

Conductivity (of both heat and electricity) and malleability.
What happends to valence electrons in an ionic bond?
In bonds between metals and non- metals thety are transferred rather than shared
How are metallic bonds different to covalent bonds?
Metallic bonds are bonds between metals. They consist of valence electrons in delocalized bonds covering the whole crystal. These electrons can move freely and are responsible for the special properties of metals such as electrical conductivity. Covalent bonds are electrons being shared and are usually between non-metals. They are localized to the atoms which are sharing them, resulting in individual molecules.
What does a covalent bond consist of?
covalent bonds are between non-metals only
What is a single covalent bond between two atoms?
It is one pair of electrons shared between two non-metals.
