Substances that can eat through metals and other containers are classified as corrosive materials. These substances can cause damage through chemical reactions, often resulting in degradation or deterioration of the material they come into contact with. Common examples include acids, bases, and certain salts. Proper handling and storage of corrosive materials are essential to prevent accidents and ensure safety.
Among the alkali metals, the tendency to react with other substances increases form top to bottom within the group.Accompanying link shows the reaction from lithium through to cesium
Aluminum is not classified as a semi-metal; it is classified as a metal. Semi-metals, or metalloids, have properties that are intermediate between metals and non-metals. Aluminum is known for its lightweight, malleability, and high conductivity, which are characteristic of metals. Therefore, aluminum is correctly classified simply as a metal.
No, elements in group 2 are classified as alkaline earth metals, not alkali metals. Alkali metals are found in group 1 of the periodic table.
Metals are good conductors of heat and electricity, while nonmetals are poor conductors. Metalloids have properties that are intermediate between metals and nonmetals.
No, metals are not usually sour. Sourness is a taste associated with acidic substances, not metals. Metals are typically characterized by properties such as conductivity, malleability, and luster, but they do not have a taste profile like food substances do.
Most elements on the periodic table are classified as metals, with only a few elements classified as non-metals.
Electric current passes through substances called "conductors", as well as "semiconductors". Conductors include all metals, and any liquid with ions in it.Electric current passes through substances called "conductors", as well as "semiconductors".

Non-metals
There are 38 elements classified as transition metals in the periodic table.
Aluminum is not classified as a semi-metal; it is classified as a metal. Semi-metals, or metalloids, have properties that are intermediate between metals and non-metals. Aluminum is known for its lightweight, malleability, and high conductivity, which are characteristic of metals. Therefore, aluminum is correctly classified simply as a metal.

Metals are good conductors of heat and electricity, while nonmetals are poor conductors. Metalloids have properties that are intermediate between metals and nonmetals.
The vast majority of elements in the periodic table can be classified as metals. Metals make up the s-block, d-block, and f-block of the periodic table. There are even a few elements in the p-block with metallic properties called metalloids.
Elements can be classified as metals, metalloids, and non-metals.
Metals and nonmetals
No, not everything has a pH level. pH measures the acidity or basicity of a solution, so it applies to substances that can be classified as acidic, neutral, or basic. Pure substances like metals or oils do not have a pH level as they do not form aqueous solutions.
