Lithium is in period 2 and potassium is in period 4.
Since potassium is in a higher period, it has more shells for electrons to lie in and therefore the valance electrons (electrons in the outer shell) are further away from the positively charged nucleus. Because of the weaker electrostatic forces between the electrons and nucleus, it is easier for the electrons to be given away and hence why it is more reactive than lithium.
What else can I help you with?
How many outer-levels electrons do lithium and potassium have?
Lithium and potassium have only one valence electron each. A valence electron is an unpaired electron available for bonding with other elements. Since lithium and potassium have only one valence electron each, they are pretty stable elements that don't do a lot of bonding.
What elementare in the alkali metal family?
Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are elements in the alkali metal family. They are highly reactive, soft metals that readily lose their outer electron to become positively charged ions.
Why do you find metal elements copper silver and gold in the ground but never find lithium sodium and potassium in the ground?
Lithium, sodium and potassium are in group I of the periodic table, which means they have a valency of 1. This makes them highly reactive with other elements, so when they are found they have most likely reacted with another element to form a compound.
Does iron react with potassium hydroxide?
Iron does not react with potassium hydroxide under normal conditions because iron is a less reactive metal compared to potassium. Potassium hydroxide is a strong base that can react with more reactive metals such as aluminum and zinc, but typically not with iron.
What is a metal that floats in water?
If you're floating metal on water, there are only a couple or three metals that have a density so low that they'll float on water. Those metals are lithium, potassium and sodium. Any one of these will float on water, and they are listed in order of increasing density with sodium just a bit less dense than water. Note that all of these metals will react violently with water, so we're setting this issue aside here. Be clear about that.
What is the name of ionic compound Kl?
You won't find KI on the periodic table, but you will find K and I. K is potassium (#19) and I is iodine (#53). Potassium is an alkali metal and iodine is a halogen. They are both very reactive and react readily with each other to form potassium iodide, which is KI, a white, bitter tasting solid.
Where would you find the chemically active metals in a periodic table?
Chemically active metals are typically found on the left side of the periodic table in Groups 1 and 2. These include metals such as lithium, sodium, potassium, magnesium, calcium, and more. These metals easily react with other elements due to their tendency to lose electrons.
How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate assuming that you have an adequate amount of lead sulfate to do the reaction?
To determine the number of grams of lithium nitrate needed to make 250 grams of lithium sulfate, you need to calculate the molar mass of lithium sulfate and lithium nitrate, then use stoichiometry to find the ratio of lithium nitrate to lithium sulfate. Finally, apply this ratio to find the mass of lithium nitrate needed for the reaction. Lead sulfate is not involved in this calculation as it is not part of the reaction between lithium nitrate and lithium sulfate.
What is the atomic number of hydrogen of lithium?
We can find lithium as a metal element. Atomic number of it is 3.
What volume of 1.050 M potassium hydroxide is required to react with 22.2 ml of 0.755 M nitrous acid?
First, calculate the number of moles of nitrous acid using the concentration and volume. Then, based on the balanced chemical equation for the reaction between potassium hydroxide (KOH) and nitrous acid (HNO2), determine the mole ratio between them. Use this ratio to find the volume of potassium hydroxide required to react with the calculated moles of nitrous acid.
Why is it highly unlikely to find potassium in the ground?
Potassium is a highly reactive metal that is not typically found in its pure form in nature. Instead, it is usually found bonded with other elements in minerals like sylvite and carnallite. The process of extracting potassium from these minerals is costly and complex, which is why it is not commonly found in the ground.
How do you get the atomic mass of lithium?
To find the atomic mass of lithium, you would look at the periodic table and find the atomic number for lithium, which is 3. The atomic mass is typically located directly below the element symbol, which for lithium is around 6.94 grams per mole.
