High luster, reacts with air on contact so must be stored under kerosene, Soft metals that can easily be cut with a knife.
the answer is Lol
High luster, reacts with air on contact so must be stored under kerosene, Soft metals that can easily be cut with a knife.
Group 1 metals, such as lithium, sodium, and potassium, are shiny, soft metals with a silvery appearance. They are highly reactive and tend to tarnish quickly when exposed to air, forming a dull oxide layer on the surface. Group 1 metals are typically stored under oil to prevent them from reacting with moisture and oxygen in the air.
Group 1 elements, also known as alkali metals, are typically shiny and have a silvery appearance when freshly cut. They are soft and can be easily shaped, with lithium, sodium, and potassium being particularly notable for their metallic luster. However, due to their high reactivity, they quickly tarnish in air, forming a dull oxide layer. These elements are characterized by low melting and boiling points compared to most metals.
A crayfish is a crustacean that has a similar appearance to the shrimp. When referring to a group of crayfish you simply call them by the same name.
Potassium belongs to Group 1 of the periodic table, also known as the alkali metals. It is a highly reactive metal that is soft and silvery-white in appearance. Potassium is known for its role in maintaining fluid balance and nerve function in the human body.
Chromium is the element in period 4 and group 6.
Group 1 metals, also known as alkali metals, include elements such as lithium, sodium, and potassium. These metals are shiny, silvery in appearance, and are soft enough to be easily cut with a knife. They are highly reactive and typically stored under oil to prevent them from reacting with air or moisture.
Sodium belongs to the group 1 of the periodic table, known as the alkali metals group.
