The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium<span> (Li), </span>sodium<span> (Na), </span>potassium<span> (K), </span>[note 1] rubidium<span> (</span>Rb), caesium (Cs<span>), </span>[note 2]<span> and francium (Fr). </span>
All the elements of group 1 in the periodic table are known as alkali metals. These are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (fr).
Characteristics of alkali metals are as follows.
Alkali metals are soft and can be cut with a knife.
They are good conductors of heat and electricity.
They have only 1 electron in their outermost sub-shell.
The equilibrium expression shows the ratio between
products and reactants. This expression is equal to the concentration of the
products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
The area where the blast originates is referred to as <span>Scene Perimeter/Isolation Zone. This whole area is dangerous for people since it can contain harmful gasses or falling debris depending on the environment of the blast.
