Which one is the most reactive metal potassium lithium or sodium?
Potassium is the most reactive of the three metals (potassium, lithium, and sodium). It reacts vigorously with water, producing hydrogen gas and heat. Sodium is less reactive than potassium, while lithium is the least reactive among the three.
Which element in the 2 period has the greatest atomic radius?
Neon (Ne) in the second period on the periodic table of the elements has the highest atomic number in that period of 10.
What metal is very chemicaly reactive?
Metals are highly reactive because of their characteristic electronic configuration, that is, the electrons in the atoms of metals have high tendency to leave their respective atoms and react with other species which have high tendency to accept electron.
Which element is more reactive lithium or barium?
Definitely lithium. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal and are on the same period. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.
Which elemets are in the second period?
The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
What are the two highly reactive elements in period 4?
the metal potassium and the nonmetal bromine
What are the 2 most reactive element found in the second period?
lithium and fluorine
How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
What element is in the same period as helium and has only one valence electron?
The element in the same period as helium that has only one valence electron is lithium. Both helium and lithium are located in Period 1 of the periodic table, with helium in Group 18 (noble gases) and lithium in Group 1 (alkali metals). Lithium has the atomic number 3 and has one electron in its outermost shell, making it highly reactive.
Which one is the most reactive metal potassium lithium or sodium?
Potassium is the most reactive of the three metals (potassium, lithium, and sodium). It reacts vigorously with water, producing hydrogen gas and heat. Sodium is less reactive than potassium, while lithium is the least reactive among the three.
Is elements H and Li in the same period in the periodic table?
No, hydrogen is in period one and lithium is in period two.
Which element in the 2 period has the greatest atomic radius?
Neon (Ne) in the second period on the periodic table of the elements has the highest atomic number in that period of 10.
What group family or column is it on the periodic table is sodium in?
Sodium is in Group 1 of the periodic table, which is also known as the alkali metals. This group includes elements like lithium, potassium, and rubidium. Alkali metals are characterized by having one electron in their outermost shell, which makes them highly reactive. Sodium is specifically located in Period 3 of the table.
What is the chang ein the atomic radio for the elements in period 2 from lithium to neon?
42
What metal is very chemicaly reactive?
Metals are highly reactive because of their characteristic electronic configuration, that is, the electrons in the atoms of metals have high tendency to leave their respective atoms and react with other species which have high tendency to accept electron.
List eight elements from period 2?
these elements are lithium, berylium, boron, carbon, nitrogen, oxygen, fluorine and neon.
Is Sodium a period 3 element that is highly reactive?
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
