Potassium is more similar to lithium because they both belong to the alkali metal group in the Periodic Table, which share similar chemical properties. Lead, on the other hand, is a metal from a different group and has different physical and chemical properties compared to both potassium and lithium.
What else can I help you with?
What is one difference between lithium and potassium?
Lithium and Potassium are very similar, however the are some differences. Potassium has more density because its atoms have more mass. Also potassium has a lower melting point and a lower boiling point. Potassium is also more reactive than Lithium because as you go down Group 1, the alkali metals become more reactive because the outer electron is more easily lost, because its further from the nucleus.
Does lithium tarnish in moist air more quickly than potassium?
Yes, lithium tarnishes more quickly in moist air compared to potassium. Lithium is highly reactive and will react with moisture in the air to form a dull coating of lithium hydroxide and lithium carbonate, leading to tarnishing. Potassium, on the other hand, tends to tarnish more slowly in moist air because it is less reactive than lithium.
What are two differences that you would see between the reaction of lithium with water and that of potassium with water?
One key difference is the rate of reaction - potassium will react more vigorously and produce more heat compared to lithium. Another difference is that the reaction of potassium with water will produce more hydrogen gas compared to lithium's reaction.
Which of properties does lithium have a larger value than potassium?
The potassium is larger radius because it has more electron shells.
Lithium and potassium which is more reactive?
Potassium is more reactive than lithium. This is because the reactivity of an alkali metal increases as you move down the group in the periodic table. Potassium is below lithium in the periodic table and has one more electron in its outer shell, making it more readily give up that electron to form compounds.
Are the properties of sodium Na more like the properties of lithium or magnesium?
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg

What two elements have the same chemical property that are similar to sodium?
There are more then two: potassium and lithium are the nearest, and there are rubidium, cesium, and francium as well in this group.

Which element reacts more rapidly in water lithium or potassium?
Potassium (K) reacts most rapidly with water.
Why does potassium have a higher first ionization energy than lithium?
Potassium has a higher first ionization energy than lithium because potassium has one more electron shell than lithium, making it harder to remove an electron from the outer shell. As electrons are added further away from the nucleus, the attractive force of the nucleus on the electrons decreases, requiring more energy to remove an electron from the outermost shell in potassium compared to lithium.
Is lithium more reactive than copper?
Yes, potassium is more reactive than lithium, since although they both need to lose one electron to have full outer shells, potassium's outer electron is furthest from the positive attractions of the nucleus. Therefore, it is easier for potassium to lose its outer electron than it is for lithium. hope that helped
What is more reactive lead or lithium?
Lithium is more reactive than lead. Lithium is a highly reactive metal and can react violently with water. Lead, on the other hand, is a relatively stable metal and does not react as readily with other substances.
Which is more reactive sodium or lithium or potassium?
Potassium is more reactive than lithium, which is more reactive than sodium. This trend is based on the alkali metal group's reactivity, with reactivity increasing as you move down the group due to the decreasing ionization energy and increasing atomic size.
