∙ 11y agoElements in group 2 except beryllium react violently with mineral acids. They react with water considerably fast and lower elements may even cause explosions. Some of their salts including oxalates and phosphates are insoluble in water.

In an electron dot diagram of potassium There is one dot. In an electron dot diagram of silicon there are four dots. Which element would you expect to be more reactive?
silicon
Is Ca the most active element?
No, it is not. The most reactive element is would be francium. The most reactive element that can be gathered in any appreciable quantity is cesium.
What element would you expect to behave the most like calcium?
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
Which element would you expect to be located in group 1 of the periodic table?
Hydrogen, lithium, sodium, potassium, rubidium, cesium and francium are the elements located in group 1 of the periodic table.
Predict reactivity of francium with cold water?
The reactivity of francium with water would be more reactive than most of the other alkali metals, because the lower down the column of alkali metals you go in the periodic table the more reactive the element becomes in cold water. Therefore, if francium was to react with cold water it would react by giving off an explosion.
Would you expect cesium element 55 to be more or less reactive than potassium?
more reactive
Would you expect to find lithium as an uncombined element in nature?
No, lithium is very reactive metal and you would expect it find it as one of the ions ion present in minerals.
Which element would be most reactive?
Fluorine is the most reactive element.
What is the least reactive element in the group 2 of the periodic table of elements?
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
What is the reactivity of caesium?
Caesium is the 5th element in group I of the periodic table. It is an alkali metal, and they become more reactive as you go down the group from lithium to sodium to potassium etc. So we would expect that caesium is highly reactive, even more reactive than rubidium.
Which element would be most reactive be sr or ba?
Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
Would a metal in group 13 be more or less reactive than a metal in group 1 in the periodic table?
It would be less reactive because the effective nuclear charge of the alkali-metals is lower than that of group 13. The result is that the valence electron is easier to attract/ionize to form bonds.
Would carbon or fluorine atom be more reactive?
Fluorine would be more reactive. Fluorine is the most reactive element.
