Question

15. Explain in brief the position of hydrogen in the modern periodic table.​

Answer 1

Answer:

Explanation:

Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals.Dhuʻl-H. 25, 1441 AH

Atomic Number: 1

Atomic Weight: 1.0079

Electronic Configuration: 1s

Answer 2

Answer:

We are all aware of our Modern Periodic table. But it took chemists years and many attempts to arrive at our current periodic table. And one main point of contention in the previous attempts was the position of hydrogen in the periodic table. Let us take a look at the unique position of hydrogen in the periodic table.

So if you glance at the periodic table, you will see hydrogen is the first element in the table. It is the smallest element on the table. It has atomic number one, which means it has only one electron orbiting it its shell. In fact, Hydrogen has only one shell. It is also the lightest element on the periodic table.

Now we know that the position of elements on the periodic table largely depends on their electronic configuration. Hydrogen has the electronic configuration of 1. It can get rid of one electron to attain noble gas configuration. This characteristic of hydrogen matches those of alkali metals. But they hydrogen atoms can also gain one electron similar to halogens.
