The most reactive halogens - fluorone and chlorine - are in the upper part of the group.
Yes, potassium is more reactive than iodine. Potassium is a highly reactive alkali metal, while iodine is a nonmetal that is less reactive. Potassium reacts vigorously with water and air, while iodine is less reactive under normal conditions.
The most active metals on the periodic table are found in the lower left (Group 1: alkali metals) and the upper right (Group 17: halogens). Alkali metals are highly reactive due to their low ionization energies, and halogens are also very reactive because they have high electronegativities and easily gain electrons to form stable ions.
Halogens are elements found in group 7 of the periodic table. They are very reactive as they have seven electrons on the outer shell and are only gaining one more to stabilise. This makes them very reactive and alkali. Fluorine is the most corrosive, found at the top of group seven and astatine, the least corrosive, though is still very corrosive. The lower down an element in group seven is, the less corrosive it is.
Iodine is not considered strongly reactive. It is a non-metal element that is relatively unreactive under normal conditions. It can react with certain elements under specific conditions, but its reactivity is generally lower compared to other non-metals like chlorine or fluorine.
Cesium (Cs) is more reactive than sodium (Na) because it is located lower in the alkali metal group on the periodic table. This means that cesium has a larger atomic radius and lower ionization energy, making it more likely to lose an electron and react with other substances.

Alkali metals are highly reactive due to their low ionization energies, and halogens are also very reactive because they have high electronegativities and easily gain electrons to form stable ions.
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
The ionization energy is lower down in the group.

The reactivity is increasing, from left to right - for example halogens.
Yes, because it is lower down in the group.

no, but lower halogens have different oxidation states.
It decreases. This is because each period (row) you go down, the element has more shells. The more shells the less effective the positive nucleus is at attracting other negative atoms to bond with and gain an electron. It is made harder to attract because there is an increasingly bigger field of negative electrons in the way.
