Titanium dioxide (TiO2) primarily exhibits ionic character but also has covalent traits. The bonding within involves the transfer of electrons from oxygen atoms to the titanium atom, indicative of ionic interaction. However, because both titanium and oxygen are non-metals and the difference in their electronegativity values is not extremely high, there is also a degree of covalent bonding present. In crystals like rutile (one of the main forms of TiO2), the titanium atoms are surrounded by oxygen atoms in a way that suggests a mixture of ionic and covalent bonds. The ionic character is dominant due to the nature of the interaction and the formation of cations and anions, but the covalent character can't be ignored, especially when considering the electronic structure and the sharing of electron density between titanium and oxygen atoms. This dual bonding nature makes TiO2 a very versatile compound, used in everything from paint pigments to sunscreen.
Titanium dioxide (TiO2) is primarily considered to be an ionic compound, featuring ionic bonding between the titanium (Ti) and oxygen (O) atoms. However, it is important to note that the situations aren't always cut and dried. Titanium Dioxide can also exhibit some covalent character due to factors such as polarizability, which also influences its bonding type. Despite this, it is predominantly referred to as an ionic substance due to the considerable electronegativity difference between Oxygen and Titanium.
Titanium dioxide is widely used in various products, including sunscreens, cosmetics, and food coloring, due to its ability to scatter light and provide UV protection. When considering its use during pregnancy, the primary concern is its form and method of application. The topical application, such as in sunscreens and cosmetics, is generally considered safe during pregnancy as the skin absorption of titanium dioxide is minimal. However, caution is advised for products that may be inhaled or ingested in nanoparticle form, where there is less certainty about safety. Ingestion in small amounts, as in food coloring, is regarded as safe, but the impact of nanoparticles is still under research. It is always recommended to consult with a healthcare provider about the safety of specific products during pregnancy.

Yes, paper is composed mainly of cellulose, which is a natural polymer. Polymers are large molecules comprised of repeating structural units, and in the case of cellulose, these units are glucose molecules linked together. Cellulose is synthesized by plants and is the most abundant organic polymer on Earth. It makes up a significant portion of the cell walls in plant cells, providing structural support. When we make paper, we are essentially processing natural plant fibers, primarily from trees, to extract and reorganize this cellulose. The individual fibers intertwine, bonding through hydrogen bonds to create the sheets of paper we use. Therefore, while the process of making paper involves human intervention, its primary component, cellulose, is entirely a natural polymer, making paper a product derived from natural polymers.
