Is potassium more reactive than iodine?
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 on the lower left upper right middle upper left or lower right?
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.
What is a dangerously corrosive halogens?
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.
Is the non metal lodine strongly reactive?
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.
What is the more reactive metal Cs or Na?
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.
Is potassium more reactive than iodine?
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.

What trends the periodic table should be expected as the atomic number decreases in the halogens?
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
Why do alkali metals become more reactive the farther you go down on the periodic table?
The ionization energy is lower down in the group.

Why is lithium the least reactive in its group?
Other alkali metals have lower electronegativities.
Is the non metal lodine strongly reactive?
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.
What happens to the reactivity nonmetals as you move down a period?
The reactivity is increasing, from left to right - for example halogens.
Is barium more reactive than calcium?
Yes, because it is lower down in the group.
What is the more reactive metal Cs or Na?
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.
Do the halogens have different numbers of valence electrons?
no, but lower halogens have different oxidation states.
How does the reactivity of group 1 and 7 elements change as they move down their groups and why?
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.
