Answer 1

The answer is A. When elements form a compound, the bonds and structure of the elements change.

Step-by-step explanation:

Element:

• An element is the simplest form of matter that cannot be broken down into its constituents by physical or chemical means.
• Elements are composed of only a single type of atom.

Compound:

• Compounds are substances formed when two or more elements form chemical bonds.
• Compounds have properties entirely different from the elements they are made up of.
