Tycho Brahe was the Danish astronomer who built an observatory called Uraniborg in the late 16th century. He made accurate measurements of the positions of celestial objects and his work laid the foundation for the later advancements in astronomy.
That depends somewhat on the type of clock and when it was built.
About 2/3 of the Periodic Table of Elements is made up of Metals.
Wood isn't an element because it contains different types of atoms. It is a substance made of all sorts of various elements, such as carbon, hydrogen, oxygen and nitrogen. These elements form compounds, which are then built up to make materials such as wood.
Molecules are formed by synthesis from elements; molecules are broken by chemical reactions.
All Substances are built from Atoms
atoms, which are the basic building blocks of matter. Atoms combine to form molecules by bonding together through chemical interactions. These molecules then further combine to create substances with specific properties.
Aristotles theory stated that all substances were built from 4 elements, earth, air, fire, and water

beacuse they built walls and they thought it was complet!
The titanic was thought to be the safest ship to sail the world because of how it was built
A substance that has properties different from the chemical elements in it is a chemical compound. A chemical compound is built from chemical elements that are chemically bonded together. And the "finished product" will have chemical properties that are unique to that compound, and different from the properties of the substances that make it up.
It thought that the Sphinx at Giza was built by Khafre builder of the 2nd pyramid
