What is the least reactive metal in order?
The least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order.
Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Helium is the least reactive of the non-metallic elements. Helium is a chemical element with the atomic number and the symbol . It's an inert gas that's colourless, odourless, tasteless, and non-toxic.
- Cesium.
- Francium.
- Rubidium.
- Potassium.
- Sodium.
- Lithium.
- Barium.
- Radium.
Silver, gold, and platinum are metals with the least reactivity.
The noble gas group is the group of elements that are the least reactive. The noble gases are the last column on the right side of the periodic...
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.
Noble gasses (group 8) are the least reactive elements in the periodic table because they have a full valence shell.
Explanation: The reactivity of an element can be determined by looking at the electron configuration of the element. The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements.
The arrangement of metals as per reactivity series is: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au.
Which family is the least reactive *?
Noble gases are least reactive as they have fulfilled valence shell.
Elements c, copper, and f, mercury, are the least reactive. On the periodic table the least reactive elements (aside from the noble gases) are the transition metals that are located in the center of the table.
The arrangement of metals as per reactivity series is: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au.
- Aluminum. Atomic number is 13. It's symbol is Al.

- Iron.
- Copper. Lead is located in the carbon group. Melting point is 625 degrees Fahrenheit. It's symbol is Pb. ...
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Explanation: Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). As you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force.
The most reactive metals in the periodic tables are the alkali metals, followed by the alkaline earth metals. Was this answer helpful?
Gold is the most unreactive metal of the above-given options.
Chemical reactivity of the elements
Period - reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.
Platinum is placed below gold in the reactivity series.
What are the two most reactive metals?
Metallic character is associated with the elements that are metals. Most of the metals are hard, have high melting/boiling points, and are malleable as well as ductile. Among Sodium and Potassium, Potassium is the most reactive metal as it has lower ionization energy than sodium due to its bigger atomic size.
Hence, ICl is most reactive.
The most reactive nonmetal is fluorine.
The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements.
The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)
Calcium or potassium which are present towards the top of the reactivity series are highly reactive metals as they can displace metals present below. From the given options, calcium is placed the highest in the activity series, and so, is the most reactive metal.
