What is the 2nd most reactive family of metals?
alkaline earth metals
The alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white.
What is the third most reactive metal?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.
| Element | Reaction with water |
|---|---|
| Lithium | Quickly |
| Calcium | More slowly |
Is cesium The 2nd most reactive metal?
Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more vigorously.
Which family is the least reactive?
Noble gases
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
Why is cesium so reactive?
The higher the effective nuclear charge is, the greater the attraction is between electrons and the nucleus. Cesium’s low effective nuclear charge indicates that the nucleus does a poor job of attracting its electrons. Both of these factors make cesium extremely reactive.
What is the most reactive metal in the Alkali family?
Within the alkali metals family, reactivity increases with increasing atomic number. This makes Francium the most reactive, followed by cesium, rubidium, potassium, sodium and lithium. Francium is almost non-existent in nature so cesium is the most reactive metal of those observed.
What is the most reactive group on the periodic table?
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one, shown in blue. Click to see how the reactivity of group one metals increases down a group.
What is the second most reactive metal in the world?
What is the second most reactive metal? 1 The most reactive element is fluorine, the first element in the halogen group. 2 The most reactive metal is francium, the last alkali metal (and most expensive element). 3 The least reactive elements are the noble gases. More
What are the characteristics of alkali metals?
As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group. Alkali metals can explode if they are exposed to water.
