Why is potassium more reactive?
Therefore, potassium has an additional shell of electrons and thus 8 more electrons. This extra shell of electrons shields the attractive force exerted on the outer electron by the nucleus. As a result, less energy is required to remove the outer electron of potassium and so it is more reactive.
Why are metals like potassium so reactive?
Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells. As a result, the alkali metals tend to form singly charged positive ions (cations) when they react with nonmetals.
Why is potassium more reactive than lithium GCSE?
Potassium is more reactive than lithium although they both need to lose only one electron to have full outer shells. This is because the outer electron of potassium atom is further from the positive attractions of the nucleus compared to the outer electron of lithium.
Why is potassium more reactive than gold?
The reactivity of metals depends upon the tendency of electrons to lose electrons. Potassium readily lose electron to form cation while gold does not lose electron easily. Hope it helps.
Why is potassium a highly reactive metal whereas gold is a noble metal?
Answer: potassium and gold have 1 electron in the outer most shell but nucleus of gold is very large than potassium and can bind all electrons together so it is less reactive unlike potassium which has less nuclear charge and give 1 electron easily from its outer shell and react with other elements.
Why is potassium more reactive than lithium?
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.
Why potassium is more reactive than sodium?
But on the other hand, potassium atoms due to being larger in size than the sodium atom has low ionization energy and thus, they can lose electrons easily and are less stable and more reactive.
Why is potassium more reactive than rubidium?
The atomicsize of potassium is smaller as compared to rubidium, thus the valence shell electron (ns1) is more loosely bound in rubidium. As a result, ionisation ethalpy of potassium is more than rubidium and hence potassium is less reactive than rubidium.
Why potassium is more reactive and gold is less reactive?
Why potassium is the most reactive metal and gold is the least reactive metal? Potassium readily lose electron to form cation while gold does not lose electron easily.
Which metal is more reactive than gold?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom….The reactivity series.
Element | Reaction with dilute acids |
---|---|
Iron | More slowly than zinc |
Copper | Very slowly |
Silver | Barely reacts |
Gold | Does not react |
Is potassium more reactive than argon?
Potassium is a highly reactive metal, while argon is an inert gas. Explain this difference based on their electron configurations. Potassium is one of the element in the periodic table having atomic number 19 and electronic configuration [Ar]4s1.
Are alkali metals most reactive?
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies.
Is lithium is more reactive than potassium?
Potassium and Lithium are metals and they have the tendency to loose electrons.Lithium is smaller in size than potassium . so valence electrons are more tightly held in Li than K. Due to larger size of K the valence electrons are loosely held and easy to remove the electron from K.Hence K is more reactive.
Why are alkali metals very reactive?
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.
