Francium is the most metallic element

"Metallic" in the context of metals refers to how reactive they are. Metals tend to lose electrons when they react. More metallic elements have a weaker attraction between their outer electrons and their positively charged nuclei, due to an increasing atomic radius and electron shielding, which increases the distance between them. This decreased strength of attraction means that the outer electrons are more easily lost, hence these elements are more reactive.

I think that would definitely have to be francium. I don't exactly remember coming across this in GCSEs.

Most metallic element is Francium, Fr. It's atomic number is 87. It is extremely radioactive; its most stable isotope, francium-223, has a half-life of only 22 minutes

Metallic character increases as you move down a group and decreases as you move from left to right across a period. Therefore, the most metallic element is found in the lower lefthand side of the Periodic table. Francium is the most metallic man-made elememt and Caesium above it, is the most metallic natural element.

This is a not a complete question as it is not specified natural or synthetic element. However, I will answer considering both viewpoints.

Natural - Cesium (Cs)

Synthetic - Francium (Fr)

for a substance to be metallic, It needs to :

a. Physically - Shine, be hard as well as be good conductors of heat and electricity.

b. Chemically - Reduce quickly, Displace Hydrogen from Dilute acids and form basic oxides.

So a metal which can show above chemically characters the quickest becomes the most metallic.

We should also remember that metallic character decreases from left to right in the periodic table. So all the elements in group 1 are most metallic compared to the elements in the respective period. Similarly the metallic character increases down the group in the periodic table, so the element in the 7th Period (synthetic) or the element in the 6th period (natural) are the most metallic elements.

The most metallic man-made element is Francium (Fr) while the most metallic natural element is Caesium (Cs).

Caesium would probably be considered the most metallic element as it is the most electropositive with the most isolated outer shell electron

Francium is the most metallic element.

The most metallic element is Francium

Francium is the most metallic element

Silver. Conductivity is ranked against silver since it is the most conductive element. It abides by the definition of a metal more than the other elements

The most metallic 'man-made' element is Francium

Francium is the most elemen in the periodic table

The most metallic element is francium.

Francium because it will most readily lose its valence electron and this is the definition of metallicity.

The most metallic element is Francium (Fr)

Francium is the most metallic which is a man-made element. Cesium is the most metallic among natural elements.

Francium, however, cesium is the most metallic man made element

Francium is the most metallic element and is extremely radioactive.

Francium and Caesium have the lowest electronegativity (highest electropositivity). However, Francium is extremely radioactive and unstable.

Arguably Francium, but it is man-made so Cesium would be the most metallic naturally occurring element.

Cesium is the most natural metallic element

Francium, because this is the element that is most easily ionised. This is due to its large atomic radius, meaning that the nuclear attraction from the nucleus to the valence electron shell plays a small part, meaning electrons are easily taken away from Francium atoms.

Hi,

francium is the most metallic element and is also and alkali group 1 metal !

The metallic character of an event is dependant on its ability to lose its outer electron and how easily it can lose its valence electrons. The metallic character of a metal also increases as you would move down the group because the atomic radius of the atom increases which means there is more distance between nucleus of the atom of an element which makes it easier to lose valence electrons which is why Cesium is the metal with the most metallic character because it’s at the bottom of the group 1 metals.

The most metallic element in the periodic table is Francium (man-made).

Very interesting question! We have to consider an element's metallic character, a collection of properties we would expect to find in a metallic element. These include ease of reduction - metals tend to form positive ions to have complete shells, and the ability to displace hydrogen from dilute acids, they are above hydrogen in the reactivity series. They also are expected to form basic oxides and chlorides.

The periodic table allows us to predict the metallic character of an element. The metallic character decreases from left to right across the period. An increase in electronegativity increases an element's desire to form negative ions instead of positive ones.

Metallic character increases down a group. This is because atoms gain shells, increasing shielding and making the removal of electrons less energy-demanding.

This would tell me the most electronegative element is francium.

There is no such thing as one metal that is more metallic than another. However, potentially the word metallic in this question is more of an adjective to describe the colour of an element

Francium is the most metallic man-made element and Caesium above it, is the most metallic natural element.

The most metallic element in the periodic table is Francium which is man made. All elements of group 1 in the periodic table are highly electropositive metals where the metallic character increases down the group.

There are many elements that are metallic but francium is classed as the most metallic

Caesium is in face the most metallic element - we can determine metallic characteristic with the general trends of the periodic table metallic properties increase down the groups of periodic table and along period from left to right. The group 1 metals also known as alkali metals are the most metallic elements

The most metallic element is francium but it is a man-made element

The most metallic natural element is caesium.

in terms of chemical reactivity, I would say Francium because it is at the bottom of group 1 and reactivity increases down the group.
