What are electropositive elements? Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is hi … ghly radioactive so no one has been able to check. cesium is most electropositive element in periodic table. Ceasium.

Metal Basics Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics. 2. Reactivity: Metals are very reactive, some more than others, but most form compounds with other elements quite easily. Sodium (Na) and potassium (K) are some of the most reactive metals. A metal like iron (Fe) forms iron oxide (Fe 2 O 3), which you know as rust.

- Fluorine is a nonmetal and is the most reactive of all elements. Oxygen and chlorine are other highly reactive nonmetal elements. Fluorine is very reactive, the most reactive … of the nonmetals, but since metals react in a completely different way, there is no way to compare them to fluorine.All group 1A metals are extremely reactive.So reactive that they must be kept stored in kerosene to keep oxygen from reacting with them.alogens: fluorine, chlorine, bromine, iodine, astatine. Also oxygen and hydrogen are reactive.

What is the most reactive element? Caesium and fluorine. Group I metals are the most reactive metals as they only have one electron in their outer shell which is easy to lose; they get more reactive as you go down the periodic table as the electron is further from the nucleus and shielded by the inner electrons.

- As you go down the alkali metals row, they get more and more reactive. This is due to their atomic radii size, their outermost electrons are further away from its nucleus which results in less of an attraction-therefore more likely to give them up to achieve a noble gas configuration/ minimum energy..5k Views. Alkali metals are known for being some of 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 often have an oxidation state of +1.

Which Metals Conduct Electricity? You may be surprised to learn that copper is not even the most conductive metal despite being used in many common applications (and the fact it is used as the measuring stick for rating conductivity in metals). Another common misconception is the pure Gold is the best conductor of electricity. While Gold does have a relatively high conductive rating, it is actually less conductive than Copper. Which metal conducts electricity the best?

Silicon - Si Silicon is the most abundant electropositive element in The Earth’s crust. It’s a metalloid with a marked metallic luster and very brittle. It is usually tetravalent in its compounds, although sometimes its bivalent, and it’s purely electropositive in its chemical behaviour. Moreover, pentacoordinated and hexacoordinated silicon compounds are also known.

What is the most reactive element in group 1? The most reactive element in the group 1 of periodic table is Caesium and Francium is not considered as it is radioactive. Caesium may under go radioactive disintegration but it can be considered as stable as compared to Francium whose half-life is too small.

Oxides The more electropositive the central atom the more basic the oxide. The more electronegative the central atom, the more acidic the oxide. Electropositive character increases from right to left across the periodic table and increases down the column.

What Is the Most Reactive Group of Metals? Quick Answer. The most reactive group of metals on the periodic table are the alkali metals. These metals are so reactive that they are not found naturally by themselves; they are found in nature as parts of compounds. The alkali metals consist of the elements lithium, sodium, potassium, rubidium, cesium and francium. These elements have a single electron in their outermost electron shells. To become more stable, atoms want to keep eight electrons in these outermost shells.

Fluorine Fluorine, the lightest of the halogens, is the most reactive of all the elements. It forms compounds with all the elements except the noble gases. The reactivity of pure fluorine gas is remarkable. Ordinary substances like wood and rubber burst into flame when held into a stream of fluorine. Even asbestos reacts so vigorously that it becomes incandescent.

Periodic table Fluorine is the most electronegative of the elements. Oxygen is more electronegative than hydrogen and so in water (H2O) the oxygen 'pulls' the electrons closer to itself and become slightly negative, and the hydrogen's slightly positive, this is called a permanent dipole. Due to this effect water has many properties that make it unusual and important to living things.

Sodium Like the other alkali metals, lithium has a single valence electron that is easily given up to form a cation. Because of this, lithium is a good conductor of heat and electricity as well as a highly reactive element, though it is the least reactive of the alkali metals.

What is the most reactive element? Like all the group 1 elements, they are very reactive. They must be stored under oil to keep air and water away from them. group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.he reactivity of the alkali metals increases down the group. Lithium is the least reactive and potassium is the most reactive of the three. The hydrogen ignites immediately during the reaction between potassium and water with the potassium producing a lilac coloured flame. Page: 1  1. 2  2. 3  3. 4  4.

What element is the best electrical conductor? Report Abuse. The best electrical conductor are superconductors. But it is not an element. Among other metals Aluminium,copper,gold ,platinum,silver etc ar very good conductors. But to use gold, silver and platinum is not at all economic.he best conductor is silver. Then Copper Here is a list of specific resistance in Ohms*mm^2/m-Silver - 0.016 - Copper - 0.0175 - Gold - 0.022 - Aluminium 0.0278 Those are the best conductors according their rank. There are non-metallic conductors.
