The most active element in Group 17 is FLUORINE .
What is the most active element?
The most chemically active element is fluorine , and it is so reactive that it cannot be found in its elementary form in nature.
Which element of group 17 is most reactive and why?
- A. electronegativity.
- B. small size.
- C. extremely high oxidising power and low dissociation energy of F-F bond.
- D. all the above factors are responsible for high reactivity of fluorine.
Why is fluorine the most active element in group 17?
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.
Which is the largest element in group 17?
| Group 17 Elements (Halogens) | Name Symbol | iodine I | astatine ( 1 ) At |
|---|
Why is group 17 so reactive?
Halogens are nonmetals in group 17 (or VII) of the periodic table. ... Due to their high effective nuclear charge, halogens are highly electronegative . Therefore, they are highly reactive and can gain an electron through reaction with other elements.
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.
Which element is most likely to bend without breaking?
Cobalt is the element which is most likely to bend without breaking. Explanation: Elements can be of two type: metals and nonmetals. Metals are ductile that is the can be drawn into small wires and they can be bent without breaking.
What is the most active nonmetal element?
Chlorine . The most active nonmetal in any period is second to last (halogens), right before the noble gases.
What are the 7 diatoms?
Key Takeaways: Diatomic Elements
There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine . These elements can exist in pure form in other arrangements.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine , the rarest naturally occurring element on Earth.
Is fluorine more reactive than oxygen?
Flourine is most reactive element . This is so because N ,O and F have 5 ,6,7 electrons resp in their valence shell. thus, fluorine requires only one electron to complete its octet in comparison to nitrogen and oxygen, which require 2 and 3 electrons respectively. so the chemical reactivity increases from N to F.
What is Group 17 on the periodic table 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).
What is the 17 elements?
| Halogen Density | Chlorine 0.0032 | Bromine 3.1028 | Iodine 4.933 | Astatine |
|---|
Why are group 17 called halogens?
The group 17 elements include fluorine(F), chlorine(Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. They are called “halogens” because they give salts when they react with metals.
What does the octet rule state?
...are expressed by his celebrated octet rule, which states that electron transfer or electron sharing proceeds until an atom has acquired an octet of electrons (i.e., the eight electrons characteristic of the valence shell of a noble gas atom). When complete transfer occurs, the bonding is ionic.
