Francium and Fluorine. They would react instantaneously and explosively.
However, this would never be done in an open lab. , because francium is radio-active.
However, Sodium (Grp (I)) and Chlorine (Grp(VII)), will react in a gas jar in the lab. But less vigorously than the above two.
What else can I help you with?
How do group II elements differ in vigor as they react with water?
Group II elements become more vigorous as you move down the group when they react with water. For example, beryllium reacts slowly with water, while magnesium reacts more vigorously. Calcium, strontium, and barium react even more vigorously, with barium being the most vigorous among the Group II elements in water.
What group of elements is most likely to react with water?
Alkali metals, such as sodium and potassium, are most likely to react vigorously with water. This reaction produces hydrogen gas and a strong alkaline solution.
What do these have in common hydrogen lithium sodium potassium?
These elements are all alkali metals. They belong to the same group (Group 1) in the periodic table, have similar chemical properties, and react vigorously with water to form alkaline solutions.
What group on the periodic table reacts with water and air?
Group 1 elements, also known as alkali metals, react vigorously with water and air. This group includes elements such as lithium, sodium, and potassium. When exposed to water or air, alkali metals can form hydroxides or oxides, respectively.
Which group of elements reacts violent with elements in group 1?
Francium would react most violently with hydrochloric acid but all of them would react violently. Cesium and Rubidium would certainly react explosively. Potassium would be very violent and catch fire. Sodium would be quite violent.
How do group II elements differ in vigor as they react with water?
Group II elements become more vigorous as you move down the group when they react with water. For example, beryllium reacts slowly with water, while magnesium reacts more vigorously. Calcium, strontium, and barium react even more vigorously, with barium being the most vigorous among the Group II elements in water.
What group on the periodic table reacts violenty with water?
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
What group of elements is most likely to react with water?
Alkali metals, such as sodium and potassium, are most likely to react vigorously with water. This reaction produces hydrogen gas and a strong alkaline solution.
Do acids react vigorously with many metals?
They do react vigorously.
Why are the group 1 elements kept in parraffin?
Since they are alkali metals which react vigorously with most compounds in the environment, especially water. They need to be separated from the environment lest they explode.
Which groups of elements are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
What do these have in common hydrogen lithium sodium potassium?
These elements are all alkali metals. They belong to the same group (Group 1) in the periodic table, have similar chemical properties, and react vigorously with water to form alkaline solutions.
What is special about the elements in the same group?
elements are in the same group since they react similarly to other elements in that group.
What group on the periodic table reacts with water and air?
Group 1 elements, also known as alkali metals, react vigorously with water and air. This group includes elements such as lithium, sodium, and potassium. When exposed to water or air, alkali metals can form hydroxides or oxides, respectively.
What is the part of the periodic table that has elements that do not chemically react?
All of them tend not to react with each other until you get lower down the group
What is magnesium reactive with?
Magnesium is reactive with oxygen, water, and acids. It can react vigorously with oxygen to form magnesium oxide, with water to form magnesium hydroxide and hydrogen gas, and with acids to form magnesium salts and hydrogen gas.
Which group of elements reacts violent with elements in group 1?
Francium would react most violently with hydrochloric acid but all of them would react violently. Cesium and Rubidium would certainly react explosively. Potassium would be very violent and catch fire. Sodium would be quite violent.
