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.
What common characteristic is generally shared by the elements at the center of a period?
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.
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
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 is the chang ein the atomic radio for the elements in period 2 from lithium to neon?
42
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.
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.
The elements cesium Cs Barium Ba and lutetium Lu appear from left to right in Period 6 of the periodic table Among these elements the most reactive is?
The most reactive element among cesium (Cs), barium (Ba), and lutetium (Lu) is cesium (Cs). Cesium is located at the far left of Period 6 in the periodic table and has a single valence electron, which makes it highly reactive.
Which of the given elements has the smallest atomic radius in 3rd period in periodic table?
Lithium(520)
