False. Many elements easily react, such as those in the Alkali Metals and Alkaline Earth Metals, VI, and halogen groups. Other elements react only under the right conditions, such as the transition metals. Some elements, such as the noble gases, do not react or react only under very stringent conditions.
Being very reactive these elements react quickly and form compounds.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
Each chemical element has a specific chemical symbol; see the link below for the list of chemical elements with symbols.
an element is chemically active till it does not attain an inert gas configuration.
Compounds are chemically mixed. You can't see the ingredients, elements, etc. in compounds. Compounds make a new thing. Compounds can't be separted easily. Compounds can't contain mixtures. Mixtures are not chemically mixed. You can see the ingredients, elements, etc. in the mixture. Mixtures don't create anything new. Mixtures can be separated easliy. Mixtures can contain compounds. Both mixtures and compounds are mixes of things. Both mixtures and compounds contain 2 or more elements, ingredients, etc. Hope I helped!
no
The organic compounds decompose off easily in the environment. This is an example of organic compounds in the sentence.
The elements in group 1 combine easily with other elements to form compounds because they are trying to get rid of their extra electrons. That is why, for example, potassium will react strongly in water. Hope this helps.
Oxygen combines easily with many other elements and compounds
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
Being very reactive these elements react quickly and form compounds.
Alkali metals and halogens.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
It depends on the substance. Most substances can exist in the gas phase. Though typically compounds that evaporate easily are nonmetals or nonmetal compounds.
Usually mixtures are easiest to separate into their substances.
Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
