Define element and compound?

Question

Answer

Elements are the simplest complete chemical substances. Each element corresponds to a single entry on the periodic table. An element is a material that consists of a single type of atom. Each atom type contains the same number of protons.Elements cannot be divided into smaller units without large amounts of energy.

Compounds, on the other hand, can have their bonds broken with practical amounts of energy, such as the heat from a fire.

Answer

An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.

Answer

Element:

An element is a pure substance that cannot be broken down into simpler substances by chemical means. It is composed of atoms of the same type. Elements are the building blocks of matter and are represented on the periodic table. There are 118 known elements, each with its own unique set of properties.

Key Points:
- Elements are made up of atoms of the same type.
- They cannot be broken down into simpler substances by chemical means.
- Elements are represented by symbols on the periodic table.
- There are 118 known elements.

Compound:

A compound is a substance composed of two or more different elements chemically combined in a fixed ratio. It has properties that are different from the elements that make it up. Compounds can be separated into their constituent elements through chemical reactions.

Key Points:
- Compounds are made up of two or more different elements.
- They are chemically combined in a fixed ratio.
- Compounds have properties that are different from the elements that make them up.
- Compounds can be separated into their constituent elements through chemical reactions.

Difference between Element and Compound:

Key Points:
- Elements are made up of atoms of the same type, while compounds are made up of different elements.
- Elements cannot be broken down into simpler substances by chemical means, while compounds can be separated into their constituent elements through chemical reactions.
- Elements are represented by symbols on the periodic table, while compounds do not have specific symbols.
- Elements have their own unique set of properties, while compounds have properties that are different from the elements that make them up.
