What are the electrical characteristics of metals?
Good conductors as solids and liquids
What type of compounds do metal oxides form?
Bases
What type of compounds do non-metal oxides form?
Acids
What are the electrical characteristics of non-metals?
Poor conductors (insulators) as solids and liquids
How is the number of outer shell electrons linked to periodic table?
The number of outer shell electrons is the same as the (1-8/0) group numbers.
Why do elements in the same group have similar chemical properties?
They have the same number of electrons in their outer shells.
Why do noble gases not readily react?
They have full outer shells.
Why do elements in groups 1-7 (1-17) react chemically?
So that they can gain or lose electrons to achieve a full outer shell and have a noble gas electron configuration.
