Electronic configuration of first 30 elements of Periodic table.
Detailed Periodic table with electron configuration (Image).Ģ). Well, in the modern printed periodic tables, you can see the Hydrogen element being placed in the group 1 along with the alkali metals.Īpart from having similar properties as that of group 1 and group 17 elements, hydrogen element is placed in 1st group because it has similar outermost electron configuration as that of alkali metals (i.e ns 1).ġ). So where should hydrogen be placed? In group 1 or group 17? So in short, I simply want to say that properties of hydrogen are similar to group 1 elements as well as group 17 elements. Similarly hydrogen also exists as a diatomic molecule (i.e H 2). Hydrogen also forms oxide (i.e H 2O or dihydrogen oxide.)Īlkali metals form sulphides (like Na 2S, K 2S, etc) and hydrogen also forms sulphide (i.e H 2S).Īlkaline metals form halides (like NaCl, KCl, etc) and hydrogen also forms halide (i.e HCl).Īpart from showing similar characteristics like that of group 1 metals, hydrogen also shows similar characteristics as that of halogens (group 17 elements).įor example halogens have very high ionization enthalpy, and hydrogen also have very high ionization enthalpy.Īlso, the halogens exist as diatomic molecules (like F 2, Cl 2, etc). The same chemical property of oxide formation is found in Hydrogen also. HEX (Hexagonal) Melting point of Hydrogen 13.99 K or -259.16 ☌ or -434.49 ☏ Boiling point of Hydrogen 20.271 K or -252.87 ☌ or -423.18 ☏ Density of Hydrogen 0.0898 g/L Main isotope of Hydrogen 1H, 2H Who discovered Hydrogen and when?įor example, group 1 elements form oxides like lithium oxide, sodium oxide, potassium oxide, etc.

In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Hydrogen element in Periodic table.) These factors manifested differently for different people, meaning that the same factor could lead one person to prefer heat pumps and another to prefer hydrogen, depending on their overall heating preferences and understanding of the two technologies.This is a SUPER easy guide on hydrogen element. three overarching factors were identified as influencing preferences for heating technologies.heating technology preferences are not fixed at this stage, although heat pumps appear to be the favoured option in this research study.acceptability of both heating technologies is limited by a lack of perceived tangible consumer benefit, which has the potential to drive scepticism towards the switch over more generally.carbon emissions reduction is viewed as an important issue, but there is limited awareness of the need to decarbonise household heating or the implications of switching over to low-carbon heating technologies.These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK. This report for the CCC by Madano and Element Energy assesses the public acceptability of two alternative low-carbon technologies for heating the home: hydrogen heating and heat pumps.
