Answer: False
Step-by-step explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions. Example: Hydrogen

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
![H_2O](https://img.qammunity.org/2019/formulas/chemistry/high-school/6hlutk8606w2ok5nx8qbbytaae8khf510v.png)
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.Compounds can also combine to give other compounds as in the given reaction:
![BaO+CO_2\rightarrow BaCO_3](https://img.qammunity.org/2019/formulas/chemistry/middle-school/l5b6ql58dzwtjbllww2gein5e0uez88hab.png)
Thus the statement is false.
