There are no "nonmetallic metals", all metals are metallic by definition.
Metals are used in chemistry for coating of some metalloids and nonmetals
Support for the phlogiston theory came from observing that substances such as wood and charcoal released a substance (phlogiston) when burned, leaving behind ash. This was believed to explain the weight loss during combustion. Additionally, the theory was used to account for the process of rusting in metals.
No, it can not be used. Every element has colour homogeneity.
Yes, everything in the universe according to M theory is in a state of change.
Electromagnets are used in recycling metals to separate ferrous metals from non-ferrous metals. When a magnet is applied to a mixture of metals, only the ferrous metals (which are magnetic) are attracted to the magnet. This allows for efficient sorting and separation of different types of metals for recycling purposes.
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
Iron is used !
Many different metals are used. Jewelry is often based on certain expensive metals such as gold, platinum, or silver, but other metals are used as well.
