The whole of the group has valence 4, that is the dioxides are all stable and familiar compounds. All but lead form tetrachlorides, and all form tetrafluorides. Tin and lead are metallic, though, and their chemistry is dominated by a secondary valence of 2, with the tetravalent compounds being strong oxidizing agents.
True. In geometry it is sometimes helpful to group objects and look at similarities between them.
they belong to the same group.
such a type of chemical group in which carbon and oxygen are related with each other by double bond is known as keto group
Both linoleic and linolenic acids are unsaturated fatty acids with 18 carbon atoms and a COOH group in each molecule. They are both biologically important as the body cannot synthesize them.
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
A group of related minerals based on chemical similarities.
The most important criteria is the similarities between chemical properties.
mineral
These are unsaturated organic compounds.
True. In geometry it is sometimes helpful to group objects and look at similarities between them.
Some similarities between a group and a team are they are both comprised of 2 or more people. They often have similar goals or objectives in mind. Another similarities between a group and team is that they gather together for the same idea or purpose.
No silicon is an element in the same group as carbon, it has similar chemical properties but it is not carbon.
Organic chemical compounds
True. In geometry it is sometimes helpful to group objects and look at similarities between them.
Gorup 14 or 4A
they belong to the same group.
Sugar is a chemical compound or rather a group of compounds containing carbon oxygen and hydrogen, not a chemical change.
