why is potassium is more reactive than lithium?
528551
Potassium metal is indeed more reactive than lithium metal, because potassium has a more loosely bound valence electron. In direct reactions, potassium reacts more violently than lithium.

Alkaline Earth metals are very reactive because they readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons. Reactivity increases from the top to the bottom of the group.

For example.. Lithium, Potassium, Sodium, Calcium, Barium Magnesium,Aluminium, Manganese, Zinc, Nickel. The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid.

If Li+ ions in aqueous solutions have a larger entropy than their larger cousins, the delta G of LiOH dissociation should be lower than the delta G of dissociation of NaOH or KOH. ... In the case of LiOH vs. NaOH, both are strong bases.

why are polyatomic ions highly reactive. ... Polyatomic ions have group of two or more elements combined with some charges. Always charged ions are more reactive than neutral one.

The elements of lower valency are more reactive than those which have more valency. Metals with a big atomic size and non- metals with a small atomic size are more active than others. In a group, the reactivity of metals increases from top to bottom and that of non- metals decreases from top to bottom.

Yes Alkali Metals Are very Reactive in nature,they do not occur freely in nature. They are Very Reactive because they only have one electron in its' outermost shell. They tend to donate electrons to complete their octate.

Calcium is more reactive than magnesium because the calcium atom is larger than the magnesium atom.

K + ,Rb+ and Cs+ are large cations and superoxide ion is larger than oxide and peroxide ions. Since due to higher lattice energies,a large cation stabilizes a large anion,therefore these metals form Superoxides.

Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.

Alkali metals have very high reactivity, so the smaller the ionization energy count the more reactive it gets, Alkali metals have the smallest ionization energy being in Group 1 which is why they have low density. Even they (the alkali metals) should not be exposed to oxygen at all or they will easily react.

The K-alpha1 emission is higher in energy and thus has a lower wavelength than the K-alpha2 emission. A larger number of electrons follow the K-alpha1 transition (L3 → K) relative to the K-alpha2 (L2 → K) transition which causes the K-alpha1 emission to be more intense than K-alpha2.

Group 1A — The Alkali Metals. ... Because the alkali metals are very reactive, they are seldom (if ever) found in their elemental form in nature, and are usually found as ionic compounds (except for hydrogen).

Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. ... All these characteristics can be attributed to these elements' large atomic radii and weak metallic bonding.

Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

The most reactive kind of metallic element is an alkali metal of group 1 (e.g., sodium or potassium); this is because such an atom has only a single valence electron; during the formation of an ionic bond which provides the necessary ionization energy, this one valence electron is easily lost to form a positive ion ( ...

Alkali metals and halogens react in different ways, and there is no standard for comparison. Halogens will react with most metals much more vigorously than alkali metals will, but alkali metals will react more vigorusly with non-metals than halogens will.
