what are metalloids
what are oxide and explain their types
Answers
Answer:
A metalloid is a type of chemical element which has properties in between, or that are a mixture of, those of metals and nonmetals.
Oxides are chemical compounds with one or more oxygen atoms combined with another element (e.g. Li2O). ... Based on their acid-base characteristics oxides are classified as acidic, basic, amphoteric or neutral:
Types of Oxides
Based on their acid-base characteristics oxides are classified as acidic or basic. ...
Acidic oxides are the oxides of non-metals. ...
Acidic oxides are, therefore, known as acid anhydrides, e.g., sulphur dioxide is sulphurous anhydride; sulphur trioxide is sulphuric anhydride.
Basic oxides are the oxides of metals.
hi
buddy ✌️✌️✌️✌️
Metalloids ......
Metalloids have properties of both metal and nonmetal metalloid are present in a zigzag line separating the metals and nonmetals left to right along the series reactivity decreases because the size decreases and there is metal.
Oxide .......
A combination of Oxygen and other chemical elements are known as oxide .
there are four type of oxide
- acidic oxide
it is generally formed by nonmetals so the acidic character increases left to right the oxide which will form in acidic on reaction with water is called an acidic oxide
2.. basic oxide
In generally formed by the metals and oxide that form base on reacting with water is called basic oxide .
3.. amthoteric oxide
is oxides are those which will react with both an acid or basic is called amthoteric oxide or these behave as both acid and basic .
4.. neutral oxide
these are neutral oxide they are neither acidic or basic .
Brain list pls❤️❤️❤️
