Group 1 elements, known as alkali metals like sodium and potassium, react violently with water. When alkali metals come into contact with water, they can produce hydrogen gas and release a large amount of heat, which can result in explosions or fires.
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.
These elements are the alkali metals.
Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.
This is the group 1, the alkali metals.
there are some alkali metals. It can be sodium or potassium.
All alkali metals and alkali earth metals below calcium react vigorously with acids.
All of the alkali metals, periodic column 1 excluding hydrogen in a wide form periodic table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
Examples of alkali metals include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These elements are located in group 1 of the periodic table and have similar chemical properties due to their single electron in the outermost shell. They are highly reactive and tend to form ionic compounds with non-metals.
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
