why is silver less reactive than rubidium?
16374
Atoms can either gain electrons or lose electrons. ... So these are the reasons for silver is far less reactive than rubidium because silver has less atomic radii than rubidium and more electron affinity than rubidium so it is not easy to lose one electron in silver to convert in +1 ions.

Metal oxides are generally easier to reduce than sulphides. ... For a lot of metals (lead, mercury are good examples), the metal forms a weaker ionic interaction with a "hard" ion like oxide compared to a "softer" ion like sulfide. This weakens the ionic bonding in the solid and makes the metal ion more reactive.

Group 1: Reactivity of Alkali Metals. Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1.

For example.. Lithium, Potassium, Sodium, Calcium, Barium Magnesium,Aluminium, Manganese, Zinc, Nickel. The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid.

Well, caesium is the more reactive, but good luck getting gram quantities of this metal. Caesium is a ROOM temperature liquid, and its much larger size with respect to sodium means that it is by far a more potent reactant. And in fact as we go down the Group 1, the metals become more reactive.

Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. ... All these characteristics can be attributed to these elements' large atomic radii and weak metallic bonding.

Radius and Reactivity As atomic number increases, so does an atom's radius. The outermost electron is held less tightly and escapes more readily. Therefore, the alkali metal with the higher number is more chemically reactive. This makes francium the most reactive of the alkali metals.

The number of electrons in the outermost shell of an atom determines its reactivity. ... Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.

Though both gold and platinum are among least reactive transition element metals, but still if we look at the reactivity series of metals we find that gold is more reactive than platinum.

Reactivity refers to how likely or vigorously an atom is to react with other substances (atoms, molecules, etc). ... Ceasium has lower ionization energy so it is VERY reactive. Sodium has greater ionization energy than ceasium so it is not so reactive as caesium but it's still very reactive.

Yes. The reactivity of the metal inversely correlates to its first ionization energy. That means that if a metal has a very low ionization energy then it is very reactive. Metals react by giving out electrons so if they can lose their electrons easily then they can react very fast.

It is because of pseudo-noble gas configuration (ns2, np6, nd10; 18 electron in valence shell of ion) of Ag+ or Cu+. It is due to poor shielding of ten d-electrons hence greater effective nuclear charge leading to the greater polarizing power of cations and hence greater covalent character in its compounds.

As you can see, copper is above silver in the reactivity series, meaning it is more reactive than silver, and will replace the silver in the silver nitrate compound.

Take silicon (Si), for example. It's shiny and silver like a typical metal, but it is brittle and a poor conductor of electricity.

–Neutrons = (mass # - Atomic #) = (108 – 47) = 61 – Ag – 108. Means the same as above. Silver always has 47 protons, so it is unnecessary to write it in the above format.
