Which element in Period 2 is the most reactive nonmetal?
Fluorine is identified as the most reactive nonmetal and the most electronegative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!
What element in period 2 has the most mass?
gas neon
The noble gas neon (Ne) has the highest mass among all the elements in period 2.
What element is Group 2 period 2?
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)….Group 2A — The Alkaline Earth Metals.

Is fluorine the most reactive element?
fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.
What groups are most reactive?
The most reactive metals are the elements in Groups 1 and 2. Elements in Group 1 generally lose an electron so their outer energy level is empty. Elements in Group 2 generally lose two electrons so their outer energy level is empty. These groups easily give up their valence electrons to make a compound.
What element is Group 2 Period 2?
Which element in Period 2 has zero Valency?
Valency of First 30 Elements
Element | Atomic Number | Valency |
---|---|---|
Valency of Hydrogen | 1 | 1 |
Valency of Helium | 2 | |
Valency of Lithium | 3 | 1 |
Valency of Beryllium | 4 | 2 |
Which element in Period 2 has most mass?
What are the two most reactive elements?
The most reactive elements in The Periodic Table of Elements are “ Caesium and fluorine.
Is Neon reactive or nonreactive?
Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).
Which element is the least reactive in Group 2?
beryllium
The least reactive element in group 2 is beryllium.
Which element is the most reactive?
1 The most reactive element is fluorine, the first element in the halogen group. 2 The most reactive metal is francium, the last alkali metal (and most expensive element). 3 The least reactive elements are the noble gases.
Why is fluorine the most reactive element in period 2?
The elements in period 2 are metal (lithium,beryllium)and non metal (boron,carbon,oxygen,fluorine.neon). electropositive character increase down the group and electro negative character decrease down the group that’s why fluorine is the most reactive element of second period. vidyanchalacademy.com. 1.7k views.
Which elements in period 2 have the most extreme chemical properties?
The elements in period 2 often have the most extreme properties in their respective groups; for example, fluorine is the most reactive halogen.
What is the reactivity of non-metals in period 2?
Reactivity of metal is directly proportion to electropositive character of metal.Reactivity of nonmetal is directly proportion to electronegative character of nonmetal. The elements in period 2 are metal (lithium,beryllium)and non metal (boron,carbon,oxygen,fluorine.neon).
