Which element is the most reactive sodium oxygen?

Reactivity of Group 1 and 2 elements increases as you go down the periodic table. So sodium is more reactive than lithium. Sodium will react with oxygen forming Na2O (sodium oxide). Lithium forms lithium oxide (Li2O).

Which of the following elements is the most reactive A at B i C br d CL?

Out of these four elements, fluorine is the most reactive element. Because fluorine is one of the halogens in the periodic table. Fluorine reactivity is due to the electron affinity.

What is more reactive oxygen or carbon?

Carbon is less reactive than O2, Cl2 etc.

Which element is most reactive element?

Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.

Which is more reactive N2 or O2?

N2 molecule is comparatively less reactive than O2 because of the presence of a strong triple bond between the atoms; more energy is needed to excite the valence electrons. … These electrons have higher energy and are unpaired; therefore, O2 is more reactive.

Which among of the following is most reactive?

The correct answer is Calcium.

Which is more reactive oxygen or chlorine?

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

Is nitrogen more reactive than carbon?

Why is it that nitrogen is much less reactive than either carbon monoxide or hydrogen cyanide? – Quora. Nitrogen (N2), carbon monoxide (CO), and hydrogen cyanide (HCN) each have the same number of electrons (14), but are otherwise quite different. HCN is an acid: it can react with a base to give CN- (cyanide ion).

Is oxygen more reactive than fluorine?

Fluorine is the most reactive because it has the strongest attraction for oxygen. We say that fluorine is electronegative. Since electronegativity decreases going to the left of the periodic table, oxygen is the second most reactive element on the list.

Which elements are more reactive than oxygen?

Why is chlorine more reactive than oxygen, despite its less electronegativity and larger atom size? – Quora. Despite being less electronegative than oxygen and fluorine, chlorine has the highest electron affinity of any element.

Are halogens more reactive than oxygen?

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.

Why oxygen is more oxidizing than chlorine?

Answer: Explanation: concept : In group , oxidizing power { means tendency to gain electron } decreases from top to bottom as the size increases . … Oxygen is more electronegative than Cl , hence, O is stronger oxidizing agent than Cl.

Is carbon less reactive than oxygen?

Carbon is less reactive than O2, Cl2 etc.

Is carbon more reactive than boron?

The chemical reactivity of boron depends on its form; generally, the crystalline form is far less reactive than the amorphous form. … Boron forms compounds with oxygen, hydrogen, the halogens, nitrogen, phosphorus, and carbon (only diamond is harder than boron carbide).

Is sodium or magnesium more reactive with oxygen?

Sodium is more reactive than magnesium as the value for the first ionisation energy (the energy required to remove the outermost electron from each atom in one mole of gaseous atoms of a particular element, forming one mole of gaseous +1 ions) of sodium is lower than that of magnesium.

What elements are more reactive than carbon?

Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron, may be extracted by reduction with carbon.

Which metal is most reactive to oxygen?

Aluminium, potassium and sodium have very high reactivity, and therefore exist as compounds in nature. One of the common compounds formed by metals is metal oxide. The formation of metal oxide is a redox reaction.

What metals are more reactive than carbon?

Electrolysis is used to extract aluminium from aluminium oxide, because aluminium is more reactive than carbon.

Is oxygen a reactive gas?

Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.

Which metal is more reactive?

– So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.

Which is the least reactive metal in the reactivity series?

As we can see in the series, out of all the given options gold is the least reactive metal.
