Question

Where should hydrogen be placed in the periodic table? Give reason for your answer.

Answer 1

Answer:

Hydrogen should be placed above the elements of group 1 because its electronic configuration is similar to the alkali metals and it can also be placed in group 17 because because its chemical properties found to be similar to (F, Cl, Br).

Answer 2

Answer:

The periodic table's Group 1 should have hydrogen at the top.

Explanation:

• In most cases, hydrogen is classified as a special element and is put at the top of the periodic table by itself. Because hydrogen shares some properties with both alkali metals and halogens, its location in the periodic table is unclear.
• However, because its electrical configuration is similar to that of alkali metals, it is placed in the first group, above all alkali metals, in the contemporary periodic table.
• Hydrogen, on the other hand, has properties that are distinct from those of the alkali metals due to its small size. Hydrogen is the first element in the periodic table because its atomic number is one, indicating that it contains one atom.
