Use your periodic table to enter the symbol of the element for each of the following questions.
The name given to all the elements on the left side of the periodic table which have from 1 to 3 valence electrons, conduct electricity and heat, are malleable and ductile.
The name given to all the elements on the right side of the periodic table which have from 5 to 7 valence electrons, do not conduct electricity or heat, and are brittle in texture.
The name given to all the elements on the border of metals and nonmetals which are not malleable or ductile, and sometimes can conduct electricity (semiconductors)
The vertical columns of the periodic table. These groups share common characteristics and are placed in these columns by their number of valence electrons.
The horizontal rows of the periodic table. These tell the number of electron shells or energy levels for each element.
These are the group IA elements with 1 valence electron in their outside shell.
These are the group IIA elements with 2 valence electrons in their outside shell.
These are the group VII A elements with 7 valence electrons in their outside shell.
These are the group VIII A or group 0 elements with 8 valence electrons in their outside shell. They have filled outside shells and are inert.
These are the Group B metals. They are not very reactive and their valenceelectrons can change from 1 to 3. They resist corrosion and are used for coins and jewelry.
These groups include large elements which are sometimes radioactive and some are synthetically made.
