Which element has highest metallic character? - Quora

Cesium, the metallic character increase down the group and mostly metals arevpresent in the left side of the periodic table. Since francium is radioactive it is not their in the story. We can clarify this by considering the ionization energy, which is the key property of metals. As metallic character increases ionisation energy decreases.

alkali metal | Definition, Properties, & Facts

Alkali metal: Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

What Are the Most Conductive Metals? | Reference

What Metals React With Water to Produce Hydrogen? …

Most alkali metals and alkaline earth metals react with water to produce hydrogen. The alkali metals comprise Group 1 of the periodic table, and include lithium, sodium, potassium, rubidium, cesium and …

What are the least metallic elements? - Quora

This makes sense, given that the metals are on the left and downwards generally. Therefore, the least metallic elements are the opposite: the right and uppermost elements on the periodic table. Thus, the elements Helium, Neon, Fluorine, and Oxygen are logically the least metallic. I hope this helps!

Activity series - College of DuPage - Home

2007-6-27 · In chemistry, the reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series.

Alkali metal - Wikipedia

2019-5-6 · Lithium, the lightest of the alkali metals, is the only alkali metal which reacts with nitrogen at standard conditions, and its nitride is the only stable alkali metal nitride. Nitrogen is an unreactive gas because breaking the strong triple bond in the dinitrogen molecule (N 2) requires a lot of energy.

2016-7-6 · This table is the Pauling electronegativity scale. There are other ways of measuring electronegativity, such as the Mulliken scale and the Allred-Rochow scale. Linus Pauling''s electronegativity scale is the most common. Note that atoms toward the upper right are more electronegative, and those to the lower left are least electronegative.

which is the most reactive metal? | Yahoo Answers

2006-8-27 · The most reactive metal is definitely not lithium you dunderheads and copys! The Most reactive metal is francium. In group one in the periodic table, the elements at the top are less reactive than the elements at the bottom of the group. And so do the reactivity of group 2 metals decrease as you go down the group.
