have oxides which are basic (i.e. react with acids to form a salt and water)
have oxides which are acidic or neutral
always solid

Metals are mostly found on which side of the periodic table?
top
bottom
left
right
Elements which are in the same group have similar properties (i.e. characteristics) and often react in similar ways. Why?
because they have the same number of electrons
because they have the same number of electron shells
because they look similar
because they have the same number of electrons in their outer shell
Group 7 elements are called the halogens. They all have similar chemical properties, because....
they all have 7 electron shells
they all have 7 electrons
they all have the same nam
they all have 7 electrons in their outer shell
Noble gases do NOT react readily - they are very unreactive. Why?
Because they are noble
Because they have a full inner shell
Because they have a full outer shell
Because they only form covalent bonds
