Could you please explain the position of Hydrogen in the modern periodic table?

Expert Answer:

Dear Student
Hydrogen resembles both alkali metals (group I A) as well as halogens (group VII A) therefore its position is said to be anomalous.
Some of the properties of hydrogen are similar to those of the elements of certain groups, as discussed above, but this is a fact that hydrogen is a unique element whose properties do not match exactly with any of the groups in the Periodic Table. However due to partial resemblance in properties with alkali metals and monovalent nature, hydrogen is usually placed at the top of elements in group IA.
We hope that clarifies your query.
