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.
One 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.

What is the difference between lithium -6 and lithium -7?
one neutron in the nucleus.
Which one of these reacts the fastest with air lithium potassium sodium?
Potassium
How many outermost electrons do lithium and potassium have?

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.
Why is lithium harder than potassium in structure and bonding?
It is because Lithium has the smallest atomic radius of them all, because it has only two shells of electrons.So the small lithium nuclei, with their one positive charge each are more easily held together by the delocalised elextron cloud than the much larger sodium or potassium ions that still only have one positive charge each.potassium is more reactive owing to the loosely bound valence electron owing to a relatively more "electron shielding" effect.The valence electron is partially shielded from the attractive force of the nucleus by the inner electrons.Although lithium and potassium have one valence electron.The difference in hardness between lithium and potassium is primarily due to their atomic structures and bonding. Lithium has a smaller atomic radius and stronger metallic bonding compared to potassium. This makes lithium atoms more tightly packed and bonded, resulting in a harder substance compared to potassium.
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 outermost (valence) electrons does lithium and potassium have?
Both lithium and potassium are in Group I of the Periodic Table, so they both have one valence electron.

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.
Elements in group one?
Lithium, Sodium, Potassium, Rubidium, Cesium, & Francium
What is the difference between lithium 6 and lithum 7 on the periodic table?
The main difference between lithium-6 and lithium-7 is their atomic mass. Lithium-6 has a mass number of 6, while lithium-7 has a mass number of 7. This means lithium-6 has one fewer neutron in its nucleus compared to lithium-7.
What happens when Lithium nitrate and Potassium sulfate are mixed?
When Lithium nitrate and Potassium sulfate are mixed, they will exchange ions to form Lithium sulfate and Potassium nitrate. This reaction is a double displacement reaction, where the cations of one compound switch places with the cations of the other compound. This results in the formation of two new compounds.
