Metals and Non-metals

Explain how the atomic structure of metals and non-metals dictates their specific positions in the periodic table.

Relate the chemical reactions of different elements directly to the arrangement of electrons in their atoms and their resulting atomic number.

Identify that the majority of elements are metals, structurally located to the left and towards the bottom of the periodic table.

Locate non-metals primarily towards the right and the top of the periodic table.

Define metals as elements that characteristically react by losing their outer shell electrons to form positive ions.

Define non-metals as elements that do not form positive ions, noting that highly reactive non-metals like halogens react with metals by gaining electrons to form negative ions.

Describe metals and non-metals comprehensively, explaining the fundamental differences between them regarding their characteristic physical and chemical properties.
