which element is always found in nature combined with other elements

The element that is almost always found in nature combined with other elements is oxygen (O). Oxygen readily reacts with other elements to form compounds such as water (H2O), carbon dioxide (CO2), and many others.

The element that is commonly found in nature combined with other elements is oxygen (O). Oxygen is highly reactive and readily forms compounds with many other elements. In fact, approximately 47% of the Earth's crust is composed of oxygen, mostly in the form of silicate minerals like quartz and feldspar. Oxygen is also a major component of water (H2O) and is found in the atmosphere as diatomic oxygen (O2).

To determine which element is commonly found in nature combined with other elements, you can refer to periodic table and its properties. Look for elements that have a high reactivity and a tendency to form compounds. Oxygen, being a highly reactive nonmetal, fits this description. Additionally, you can study the composition of minerals, compounds, and substances found in nature to identify elements that commonly occur combined with others.
