What property of hydrogen makes it resemble with halogen?
It resembles halogens because it needs one electron to completely fill its valence shell to attain noble gas configuration. It also forms diatomic molecule, combines with metals and non-metals to form compounds.
Why hydrogen resembles alkali metals as well as halogens explain?
Hydrogen resembles both alkali metals as well as halogens. This is because hydrogen-like alkali metals donate its’ outer electron to form compounds like oxides, halides & sulfides. Also, it shares its’ electron with another hydrogen atom to form a diatomic molecule.
In what way hydrogen resembles alkali metals?
Hydrogen resembles alkali metals because it has only one electron in the outermost shell same as alkali metals. It can donate one electron and become H+.
In what way does the hydrogen resemble with halogen and alkali metal?
6) Atomicity and non metallic character: Just like halogens, hydrogen also exist as a diatomic molecule. Like halogens, hydrogen is a typical non metal. 7) Combination with metals: Hydrogen combines with highly electropositive alkali and alkaline earth metals to form metallic hydrides.
Which group of elements does hydrogen resemble and how does it resemble them?
Solution : Hydrogen resembles alkali metals, i.e.,Li,Na,K,Rb, Cs and fr of group I of the periodic table in the following respects. (i) Like alkalie metals, hydrogen also contain one electron in its outermost (valence) shall and exhibit `+1` oxidation state.
How does hydrogen differ from halogens give two points?
Answer. hydrogen differ from alkali metals because hydrogen atom has only one shell whereas alkali metals have two or more shells. hydrogen differ from halogens because hydrogen atom has only one shell where as halogens have two or more shells .
Which of the following properties of hydrogen does not resemble with that of halogens?
Solution : properties like ionisation enthalpy, reducing nature does not resemble with halogen.
What are chemical properties of hydrogen?
Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “H2“.
In what respect does hydrogen differs from halogen?
Hydrogen atoms has only one shell, but halogens have two or more shells. Was this answer helpful?
Is hydrogen a halogen?
So hydrogen is neither an alkali metal nor halogen.
Which of the following properties of hydrogen does not resemble with alkali metals?
Hydrogen shows all other properties like alkali metals (form cation, combine with halogens, reducing nature) but nature of oxide is different than metals.
In which property listed below hydrogen does not resemble with alkali metals?
Presence of one electron in valence shell.
What are the chemical properties of the halogens?
Chemical properties of the halogens. Atoms of group 7 elements all have seven electrons in their outer shell. This means that the halogens all have similar chemical properties. The halogens react with metals to produce salts (the word ‘halogen’ means ‘salt former’).
How is hydrogen similar to other halogens?
The Resemblance with Halogen Hydrogen resembles halogens, i.e., fluorine (F), chlorine (C l), bromine (B r), and iodine (l) of group 17 of the periodic table in the following respects: 1. Electronic configuration: Like halogens, hydrogen also needs one electron to attain the nearest inert (noble) gas configuration, i.e., helium.
What happens when halogens react with hydrogen?
Include state symbols. The halogens react with hydrogen to produce compounds called hydrogen halides. For example, chlorine reacts with hydrogen: The hydrogen halides are gases at room temperature. They dissolve in water to produce acidic solutions.
What are the physical and chemical properties of hydrogen?
Ans: The physical properties of hydrogen: It is a colorless, odourless, tasteless, non-metallic diatomic gas. The chemical properties of hydrogen: It shows both electropositive and electronegative properties. Hydrogen reacts with an alkali metal, and alkaline earth metals give metal hydrides. Reaction with alkali metals.
