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.

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.
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 odd one out between Li Na K and Fe?
Fe - which is the symbol for Iron. Li is Lithium Na is Sodium K is Potassium Lithium, Sodium, and Potassium are all Alkali Metals. Iron is a metal in the 1st transition series - quit a bit to the right of the alkali metals in the Period Table.
What is the number of valence electrons for Li and K?
Both lithium and potassium have one valence electron
How is the reaction of lithium and water similar to the reaction of potassium and water?
Both lithium and potassium have only one electron in their outer electron shell (the valence shell). That's what makes them members of Group 1 of the periodic table, the Alkali metals. These elements want to loan out that one electron. When water is dumped on lithium (Li) or potassium (K), they will react to form the hydroxides, LiOH and KOH, respectively. Lithium and potassium take the OH- ion (the hydroxide ion) from water, and dump an electron on the hydrogen atom to create hydrogen gas. Here are the two (balanced) equations: 2Li + 2H2O => 2LiOH + H2 (gas) 2K+ 2H2O => 2KOH + H2 (gas)
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?

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.
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.
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.
Elements in group one?
Lithium, Sodium, Potassium, Rubidium, Cesium, & Francium
What is the element lithium similar to?
Lithium has similar properties with anything in Group 1 on the periodic table.
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 the main difference between a lithium ion and a lithium polymer battery and which one is better?
They both have similar capabilities, but the main difference is that Lithium Polymer batteries can be shaped/molded in ways that Lithium Ion batteries simply can't. Lithium Polymer batteries are used in lots of hobby equipment, very small devices, and anywhere else where a certain shape of battery is required.
