O Chromium is twice as reactive as vanadium.
O Potassium is much more reactive than iron.
O Calcium is much less reactive than scandium.
O All the elements have the same reactivity.

Answer 1

The given periodic table shows the element potassium (K) on the far left of the table. The atomic mass of all the elements are displayed.  Potassium is considered to be the most reactive metal as it is easier to remove the electrons from the last shell.

Based on the given portion of the periodic table of the elements, it can be concluded that potassium is much more reactive than iron.

Thus, the correct statement is potassium is much more reactive than iron.
