Why the position of hydrogen is controversial in periodic table
Answers
Concept introduction:
Hydrogen have one electron in outermost shell hence it can accept one electro as well as donate one electron to get Nobel gas configuration.
Explanation:
Given that, hydrogen position is controversial.
We have to find, reasons behind controversy of position of hydrogen.
According to the question,
With numerous groups in the periodic table, including Alkali metals, halogens, and group IV A elements, hydrogen shares many similarities and differences.
Alkali metals and hydrogen atoms have similarities in that both have an electron in the 1s subshell that may be lost to generate H+. Alkali metals and hydrogen both have a great propensity to interact with other electronegative elements, such as halogens.
Alkali metals don't have the diatomic molecule form of hydrogen, which is one way they differ from them. Alkali are metals but hydrogen is not a metal.
Final Answer:
Since hydrogen can do both accept and donate electron to get Nobel gas configuration so hydrogen is having properties of both metal and non metal so its position is controversial.
