What two elements react the most violently?
Now among the given options, the reaction between Chlorine and potassium will be most violent. This is because according to the periodic properties the reactivity of potassium and chlorine is very high.
Which group 2 element is most reactive?
Alkali Earth Metals
Possibly the neighbours to the most reactive elements in the group, Alkali earth metals belong to the group 2 of the periodic table.
Which 2 groups of elements would be the most reactive and why?
The alkali metals are the most reactive metals. Group 2 consists of the alkaline Earth metals. They are very reactive but less so than the alkali metals.
Why are groups 1 and 2 the most reactive?
The First Group Elements in the same group of the periodic table have the same number of valence electrons. These are the electrons in their outer energy level that can be involved in chemical reactions. All the elements in group 1 have just one valence electron. This makes them very reactive.
What are the Group 2 elements called?
Alkaline Earth Metals
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What is the classification of all elements in the D block?
All the d-block elements are classified into four series which are called 3d, 4d, 5d and 6d series corresponding to the filled outer shells of 3d, 4d, 5d, and 6d orbitals.
Why are groups 1 and 17 the most reactive?
Elements in group 17 include fluorine and chlorine. Group 1 of the periodic table includes hydrogen and the alkali metals. Because they have just one valence electron, group 1 elements are very reactive.
What is the least reactive element in group 2?
The least reactive element in group 2 is beryllium. Even at red heat beryllium will not react with water and it does not react with dinitrogen (N2).
