Elements in group 17 all tend to be reactive because....

• They all all have a full outer shell, so they are ready to form a bond.

• The all need one electron to fill their outer shell

• They all are missing a proton

• They all want to give up an electron

What is true about Elements that have 7 electrons in their out shell?

• They are reactive because they want to gain an electron to fill their outer shell.

• They are stable because their out shell is full

• They are good at conducting electricity because they have extra electrons.

• They are very rare because most elements have only a maximum if six electrons in the out shell.
