Sodium, potassium, and lithium all are alkali metals. All belong to the group-first. Alkali metal forms oxides in presence of oxygen. Therefore, due to the high reactivity of alkali metals towards air and moisture, they are stored in kerosene oil.
Q. What do lithium sodium potassium rubidium and cesium have in common?
This family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium (Li, Na, K, Rb, Cs, and Fr, respectively). Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive.

Q. What is the relationship between sodium potassium and lithium?
In this dramatic demonstration, lithium, sodium, and potassium react with water to produce hydrogen gas and the hydroxides of the metals. Lithium reacts fairly slowly, fizzing.
Q. Which is the most reactive out of lithium sodium and potassium?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom….The reactivity series.
| Element | Reaction with water |
|---|---|
| Potassium | Violently |
| Sodium | Very quickly |
| Lithium | Quickly |
| Calcium | More slowly |
Q. What are the similarities between lithium sodium and potassium?
Lithium, sodium and potassium formed a group called alkali metal group. Their similar properties are: (i) All these elements are metals. (ii) All these react readily with water to form alkalies and hydrogen gas.
Q. What is the same about the electron structure of lithium sodium and potassium?
Lithium, Sodium, and Potassium have a similarity in them that is they all have one electron in their outermost orbit.
Q. Which is more metallic lithium or sodium?
Explanation: Metallic character means the reactivity of a metal. Smaller is the size of a metal more will be its ability to react. Since, Li, Na, and K all belong to the same group therefore, Li has highest metallic character.
Q. Does lithium and sodium have similar properties?
So, the elements with similar properties to sodium (Na) are all of those elements in the same Group. The ones “most” similar would be the ones closest in mass as well. Those would be Lithium (Li) and Potassium (K).
Q. Are the properties of sodium more like lithium or magnesium?
Are the properties of sodium, Na, more like the properties of lithium, Li, or magnesium, Mg? lithium; Sodium and lithium are in the same group so their properties should be more alike than the properties of sodium and magnesium.
Q. Is beryllium less reactive than lithium?
Which is less reactive: lithium (Li) or beryllium (Be)? Answer: Beryllium (Be) is less reactive because it is to the right of lithium (Li) in the period.
Q. Which one of the following is most metallic?
bismuth
Q. Which is more metallic K or CA?
Among K, Mg, and Ca, K (potassium) will be more metallic because it is an alkali metal. Calcium will be more metallic than magnesium because calcium comes in period 4 of group 4 and magnesium comes in period 3 of group 2.
Q. How do you arrange metallic characters?
The metallic character of an element decreases as you move from left to right or bottom to top of the periodic table. This is because atoms have a better ability to gain electrons to fill a valence shell than lose them to and an unfilled shell. In other words, it increases as you go from right to left or top to bottom.
