In some forms of the periodic table, hydrogen is placedin Group I; in others, it is placed in Group VII. Give arguments in favor of each location.
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.
In some forms of the periodic table, hydrogen is placed
in Group I; in others, it is placed in Group VII. Give arguments in favor of each location.
Hydrogen is placed separately in the periodic table.It shows similarities to both group 1 and group 17.
Yet it placed separately just above group 1. Hydrogen is a non-metal and is placed in the periodic table above the group since it has a structure of ns1 electrons like the alkali metals. Just like alkali metals it shows +1 oxidation state and donate one of it’s electron resulting in a stable configuration. The reason why hydrogen can be placed in both group 1 and group 17 is that in some of its characteristics it resembles Alkali metals as it can easily form cations, so it can be placed in periodic table group 1, but it also resembles Halogens in its characteristics as it forms the true halogen property
