Identify whether the following statement is true or false.In all elements, atoms are joined together by chemical bonds.

The statement "In all elements, atoms are joined together by chemical bonds" is false.

Explanation:

1. Definition of Elements: An element is a pure substance that cannot be broken down into simpler substances by chemical means. It consists of atoms that have the same number of protons in their atomic nuclei.

2. Atomic Arrangement: In many elements, such as noble gases (e.g., helium, neon), atoms exist as single entities and do not bond with each other under normal conditions. They are monatomic and are not joined together by chemical bonds.

3. Molecular Elements: Some elements exist as diatomic molecules (e.g., O₂, N₂) where atoms are bonded together, while others like carbon can form various structures (e.g., graphite, diamond), which also involve bonding.

4. Exceptions: Therefore, while most elements do form chemical bonds in various compounds, not all do in their elemental form, particularly in the case of noble gases.

Conclusion:

Since not all elements consist of bonded atoms, the statement is false.
