Question

Which changes MUST happen for elements to become a compound

Answer 1

Answer:

Chemical changes in compounds happen when chemical bonds are created or destroyed. Then the molecular structure changes; new molecules form and a new substance is created. Often heat is used to begin a chemical change, as when baking a cake. Another example of a chemical reaction is the rusting of a metal trash can.

Answer 2

An element is constituted of only atoms and no other entities are present in it. Whereas a chemical compound is a substance made up of various identical molecules of the same or different atoms.

The atoms of the same or different species bond together to form a compound.

• Chemical bonding is present among them that cannot be simply separated.

• The compounds can have ionic, covalent and hydrogen bonds present in them.

• When the new atoms combine the structure changes of the new molecule formed.
