Is the position of hydrogen fixed?
The position of hydrogen is not fixed in the periodic table, sometimes it is placed with alkali metals in 1st group and sometimes with halogens in the 17th group as it resembles with alkali metal metals as well as with halogens.
Why was there no fixed position of hydrogen Class 10?
Mendeleev's periodic law could not assign a fixed position to hydrogen in the periodic table because hydrogen resembled both alkali metals (Group 1) and halogens (Group 17) in some of its properties. Hydrogen reacts with metals to form ionic compounds called hydrides and also with non-metals to form covalent compounds.
Why H atom has no fixed position in periodic table?
Hydrogen had no fixed position in Mendeleev's Periodic table because it resembles alkali metal by forming positive ions and resembles halogens by forming diatomic molecule.
What is the problem with the position of hydrogen?
Loss of Electron: Although it has only one electron in its outer shell, hydrogen cannot easily lose this electron to gain electropositivity. All other alkali metals can do this with ease.
Why the position of hydrogen in periodic table is controversial?
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.
What is the position of hydrogen in the modern periodic table Class 10?
first element What is the Position of Hydrogen in the Periodic Table? Hydrogen is the first element of the periodic table as its atomic number is one, which means it has only one electron in its atom and thus only one electron is present in its outermost shell.
Why the position of hydrogen is controversial?
the position of hydrogen is controversial in periodic table because hydrogen is the only element with out neutron. it belongs to 1 st group but it is not placed there .
Why is the position of hydrogen in the periodic table controversial class 10?
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.
