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.

RossOne key difference between lithium and potassium is their atomic number and Atomic Mass; lithium has an atomic number of 3 and an atomic mass of around 6.94, whereas potassium has an atomic number of 19 and an atomic mass of around 39.10. Additionally, potassium is more reactive than lithium due to its position in the Periodic Table.

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.
How many outermost electrons do lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.
What is the odd one out of lithium and potassium and iron and sodium?
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.
What element is the odd one out lithium sodium potassium and iron?
Iron is the odd one out because it is a transition metal, while lithium, sodium, and potassium are alkali metals.
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.
