Compare the patterns in properties of the group 1 elements with the patterns in properties of the group 7 elements. Can you help me please with this question?

Where is the graph ?

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way. 

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

B? i feel like this is a trick
