Which group of metals is the most reactive
Where are the most reactive metals group?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Which groups are the most reactive and why?
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 most reactive metal group Why?
The most reactive metals belong to the alkali metals element group. Reactivity increases as you move down the alkali metals group. The increase in reactivity correlates to a decrease in electronegativity (increase in electropositivity.)
Which is the most reactive?
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 are the most reactive metals in order?
Reactivity series of metals
| Order of reactivity | Metal |
|---|---|
| Most reactive | potassium (K) |
| Second most reactive | sodium (Na) |
| Third most reactive | calcium (Ca) |
| Least reactive | magnesium (Mg) |
Is Group 1 or Group 2 more reactive?
The outermost electrons of the alkaline earth metals (group 2) are more difficult to remove than the outer electron of the alkali metals, leading to the group 2 metals being less reactive than those in group 1.
Are metals or nonmetals more reactive?
Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive. … Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound.
What do the most reactive metals react with?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions .

Why is Group 17 so reactive?
The halogens are located on the left of the noble gases on the periodic table. Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. … This characteristic makes them more reactive than other non-metal groups.
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 is group 1and Group 2?
Group 1 or A – highest rank job, highest pay scale , posts like district collector , commissioner , IT commissioner etc. fall into this group. Group 2 or B – 2nd in command , posts like assistant in all departments such as assistant commissioner of IT. Group 3 or C – Inspector level jobs., general employees.
What is the most reactive group of the nonmetals?
Halogens
Halogens are the most reactive nonmetals on the periodic table. The halogens are so reactive due to their electronic configuration.
What are Group 18 elements called?
noble gas
noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
What group is most reactive non metals?
halogens
Elements in group 17 are called halogens (see Figure below). They are highly reactive nonmetals with seven valence electrons. The halogens react violently with alkali metals, which have one valence electron.
What is the most reactive non metal explain?
Fluorine is the most reactive non-metal because it is the most electronegative of all of the non-metal elements of the periodic table. Due to its strong electro negativity & small size, Fluorine has a strong tendency to accept electrons from other atoms or ions.
What is Group 16 called?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What is Group 17 called?
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Why is Group 18 not reactive?
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
