List the elements that form basic oxide with oxygen?

Explanation

Solution

Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base; or react with an acid to form a salt and water which are called neutralization reactions. The word oxides referred to the chemical compounds that one or more oxygen atoms combined with another element.

Complete answer:
Group 1,21,2 and lanthanides form basic compounds of oxygen when they react with dioxygen. Because these compounds are usually ionic in nature. During the formation of these compounds, a large amount of energy is released. These compounds readily react with water except a few exceptions
The group one element reacts with oxygen from the air to make metal oxides. At room temperature, oxygen reacts with the surface of the metal. This forms a white oxide, which covers the surface.
When The Reactions of Group two Elements with Oxygen. All Group two elements tarnish in air to form a coating of the metal oxide. They react violently in pure oxygen producing a white ionic oxide. When these metals are heated in oxygen they burn vigorously to produce a white ionic oxide
Lanthanides tend to react with oxygen to form oxides. The reaction at room temperature can be slow while heat can cause the reaction to happen rapidly. The Lanthanide Contraction refers to the decrease in atomic size of the elements in which electrons fill the f-subshell.

Note:
Group one metals are very reactive, and must be stored out of contact with air to prevent oxidation. Depending on the period of the metal, a different type of oxide is formed when the metal is burned. The reactions are the same in oxygen and in air, but oxygen will generate a more violent reaction.
