What is the order of reactivity of metals?

Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > Cu > Ag. Was this answer helpful?

How reactive is the nitrogen group?

The reactivity of the heavier group 15 elements decreases down the group, as does the stability of their catenated compounds. In group 15, nitrogen and phosphorus behave chemically like nonmetals, arsenic and antimony behave like semimetals, and bismuth behaves like a metal.

What series lists the reactivity of a metal?

the activity series
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction.

How does nitrogen react with metal?

At elevated temperatures, nitrogen reacts with highly electropositive metals to form ionic nitrides, such as Li3N and Ca3N2. These compounds consist of ionic lattices formed by Mn+ and N3− ions.

Which is the correct order of reactivity series?

3) There is the order of reactivity of metals and in order to remember this order, one has to recite this order in any possible simple form. The order of reactivity of metals is as follows, Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Zinc > Iron > Copper > Silver > Gold.

Which metal has highest reactivity?

The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.

What is the reactivity of nitrogen?

Nitrogen is a rather unreactive element, and the reason is that the N≡N bond energy is 946 kJ mol−1. This lack of reactivity is somewhat unlike other nonmetals given the position of the atom in the periodic table and the fact that nitrogen is a nonmetal having an electronegativity of 3.0 (the third highest value).

Why is nitrogen in group 15?

The Nitrogen Family Group 15 (VA) contains nitrogen, phosphorous, arsenic, antimony, and bismuth. Elements in Group 15 have five valence electrons. Because the elements can either gain three electrons or lose five to gain a stable configuration, they more often form covalent compounds unless bonded to an active metal.

Which of the following elements displaces Aluminium from its salt a Zn b Fe c Ni d CA?

Answer. Aluminium Aluminium displaces zinc, copper, and iron from their solutions.

Why is nitrogen not reactive?

About 78% of Earth’s atmosphere is nitrogen. The strong triple-bond between the atoms in molecular nitrogen makes this compound difficult to break apart, and thus nearly inert. However, when nitrogen bonds do break, the resulting products are often highly reactive.

What is the order of decreasing reactivity of the metals?

Theoretical idea: Metals in the periodic table can be ordered according to their reactivity. The order in decreasing reactivity is K, Na, Li, Ca, Mg, Al, Zn, Fe, Cu, Ag, Au.

Which is the least reactive metal?

Platinum
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum.
