Which atom below is in the same group as the picture?
What metal group on the periodic table is the most reactive?
Group 1
Group 2
Group 17
Group 18
Which non-metal group on the periodic table is the most reactive?
Group 1
Group 2
Group 17
Group 18
What group on the periodic table is the least reactive and why?
Group 1, because all of the elements in it have so few valence electrons.
Group 2, because all the elements in it are metals.
Group 17, because it has 17 valence electrons in each element.
Group 18, because all of the elements in this group have a full valence level.
What determines that a group is the LEAST reactive?
It has the fewest number of electrons
tis has the greatest number of electrons
It has 8 valence electrons, or a full outer energy level
It has less than 8 valence electrons
What is a common characteristics of all of the elements in Group 18?
They have fewer than 8 valence electrons
They are all gases
They are all solids
They are all highly reactive
