Why were least reactive elements discovered before more reactive elements?
The simple reason is that least reactive elements are mostly found in their native state while reactive elements are found in combined state (in form of their compounds). It is easier to extract any element in it's native or elementary form. Such elements can be easily separated from their ore. They are separated by using physical processes. Reactive elements need to be extracted from their minerals through chemical processes which are more expensive and tedious.
Are alkali metals and alkaline earth metals always found combined in nature?
They react easily. They combine with other elements to complete/fill their outer shell.
Why scientists in 1800 could not extract aluminium from alumina?
The necessary technological conditions did not exist.
What is Lassaigne's extract?
Lassaigne test is a method in qualitative analytical chemistry used to detect halogens, sulfur or nitrogen in organic compounds.
How is gold bromine used in life?
- If you think to gold bromide this is used as catalyst in organic chemistry or for the detection of ketamine.- A bromine/bromide mixture was proposed to extract gold from minerals.
Why you use sodium extract for detection of elements?
we use sodium extract bcz it converts covalent compounds into ionic form..
Why is it necessary to prepare sodium extract for the detection of foreign elements?
We need to prepare sodium extract for the detection of foreign elements because foreign elements are found in organic compound bonded covalently. As a result they cannot be detected through organic compound directly. Hence they are first converted into ionic compound with the help of sodium extract
How are hazards associated with sodium extract preparation controlled?
Acute hazards involved in sodium extract preparation for extra elements detection is eradicated by using NOSIA. The NOSIA stands for nonbreakable sodium ignition apparatus. This apparatus provides a safer technique for sodium extract of the organic compounds.
What is Safer Technique for Sustainable Sodium Extract Preparation?
Nonbreakable sodium ignition apparatus abbreviated as NOSIA is safer technique for sodium extract preparation for extra elements detection in any organic compounds. The NOSIA is nonpolluting and Ecofriendly device and does not require breaking of ignition capillarity for extract. "critical reviewers are must who add quality to the work"
Why only sodium is used in Lassaigne's test?
because of its electropositive nature. it is cheap also. although potassium can be used but it is costly... and lithium is less electropositive... Lassaigne's test is a test for the detection of halogens, nitrogen and sulphur in an organic compound. These elements are covalently bonded to the organic compounds. In order to detect them, these have to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. The ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests. The extract is called sodium fusion extract or Lassaigne's extract.

What are the active medicinal properties of grapefruit seed extract?
Bioflavonoids, polyphenolic compounds, diphenol hydroxybenzene complex.
Can you extract elements from any kind of chemical bond?
Any bond can be destroyed.
