Sodium of table salt does not react with water like sodium metal BECAUSE it separates from chlorine as ionic sodium and ionic sodium is stable and it is solvated hence it does not react.

SODIUM CHLORIDE is generally unreactive. Releases gaseous hydrogen chloride if mixed with a concentrated nonvolatile acid such as sulfuric acid.

Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium.

Sodium is a reactive metal because it has higher tendency to lose electron because it has only one electron at its outermost orbital and by losing that electron it can get stable electronic configuration. That’s why it is a reactive metal and can get react with any other element easily.

Answer: Sodium is more reactive than lithium because sodium is larger in size. Outermost electrons are less tightly held in sodium than in lithium. As a result, sodium loses its outermost electron more easily than lithium.

Fluorine is more reactive. Fluorine wants to get to a stable 10 electrons to be like Neon. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and others and thus more strongly attracted. Fluorine is most electronegative, thus it is most reactive.

Due to the short bond length, the repulsion between non-bonding electrons is very high. Thus it makes the fluorine most electronegative because of its small radius as the positive protons hold a very strong attraction to the electrons. Hence, Fluorine is the most reactive of all the halogens due to its small size.

Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably oxides) with almost all other elements.

Alkali metals

Fluorine is the most reactive because it has the strongest attraction for oxygen. Since electronegativity decreases going to the left of the periodic table, oxygen is the second most reactive element on the list. Nitrogen is the third most reactive.

Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …

And fluorine requires only 1 electron to complete it’s octet to get stable.. Therefore Fluorine is more reactive and less stable than Nitrogen.

Oxygen needs 2 more electrons to fill the outer shell, while nitrogen needs 3 electrons. Hence, it is much easier for oxygen to complete its octet, as compared to nitrogen and that is why, oxygen is more reactive than nitrogen.

Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can’t be demonstrated in a classroom! This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

Silver, gold, and platinum are metals with the least reactivity. They are found in nature.

Stainless steel and tin (including tin-lined copper) are examples of nonreactive metals. You can use these pans for all kinds of foods, though you may not get the heat conductivity of copper or cast iron.

The terms “reactive” and “nonreactive” are referring to the type of metal from which your pot or bowl is made. Aluminum, cast iron, and copper are all “reactive.” Stainless steel, ceramic, glass, and metal cookware with enamel coating are all “nonreactive.”

Zinc is a lustrous bluish-white metal. It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen.

Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can’t be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.
