Which of the following is the least reactive?

Which of the following is the least reactive?

Black phosphorus is thermodynamically most stable form of phosphorus as it is a highly polymerised form of phosphorus. Hence it is least reactive.

Which group includes the least reactive non metals?

Noble gases

Which of the following are very reactive nonmetals?

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.

Is chlorine a less reactive nonmetal?

Originally Answered: Why is chlorine a very reactive non-metal? Chlorine is a very reactive non metals because this element don’t form any known chemical compound.

Is chlorine highly reactive?

Because it is so “anxious” to pull another electron into its orbit, chlorine is an extremely reactive element. In contrast, argon, sitting next to chlorine on the Periodic Table of the Elements, is very stable as a single atom because it has a full outer orbit of eight electrons.

Which chlorine is most reactive?

Chlorine is intermediate in reactivity between fluorine and bromine, and is one of the most reactive elements. Chlorine is a weaker oxidising agent than fluorine but a stronger one than bromine or iodine.

Is chlorine a reactive metal?

Chlorine is a halogen in group 17 and period 3. It is very reactive and is widely used for many purposes, such as as a disinfectant. Due to its high reactivity, it is commonly found in nature bonded to many different elements….Properties.

Atomic Number 17
Standard Electron Potential Cl2+2e−→2Cl− 1.358V

Is oxygen or chlorine more reactive?

Despite being less electronegative than oxygen and fluorine, chlorine has the highest electron affinity of any element. Singlet oxygen is more reactive than chlorine I believe. Chlorine is also a singlet which is why it readily attacks and bleaches organic compounds while atmospheric oxygen does not.

Which is more reactive fluorine or chlorine?

The thing that makes fluorine so reactive is its electronegativity. Electronegativity is the tendency of an atom to attract a shared pair of electrons. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.

Why chlorine is more reactive than nitrogen?

Answer: Because of the presence of lone pairs in nitrogen it further adds to its reactivity. Hence nitrogen is more electronegative than chlorine. Chlorine is less reactive than nitrogen in other words nitrogen is more reactive than chlorine .

What is the electronegativity difference between chlorine and oxygen?

Electronegativity Chart

Element Electronegativity, as measured by the Pauling scale
Oxygen 3.44
Fluorine 3.98
Sulfur 2.58
Chlorine 3.16

Which is more electronegative fluorine or iodine?

“Fluorine is more electronegative than Iodine.” Give reason in support of this. Answer: Fluorine has smaller size than iodine, has more tendency to attract shared pair of electron towards itself.

What is the electronegativity of iodine?


Is iodine more electronegative than chlorine?

Iodine atom is less electronegative than chlorine atom, and chlorine is very happy with its extra electron since it is an electronegative element.

What kind of element has high ionization energy?


What kind of element has a less than 4 valence electrons?


Which number will give you an idea on the number of valence electrons?

The number that will give you an idea on the number of valence electrons is the Group number or the Family number. Let’s say for example Group 1A, has 1 valence electron corresponding to the number of the group, Group 7A has 7 valence electron, Group 3B had 3 valence electron and so forth.

What do you notice in the number of valence?

Answer: The metals have lesser valence electrons than non-metals and all noble gases have 8 valence electrons except for helium, which has 2 valence electrons.. The valence electron of metallic elements depend on their group number and they are having lesser valence electron than non-metals.
