Question

Like alkali metals Hydrogen also forms_________

Solution

Alkali metals:

  1. They are s-block elements that are found on the periodic table's left side. Because they lose electrons quickly, alkali metals are among the most reactive elements on the earth.
  2. They have one electron present in their valence shell and their electronic configuration is ns1
  3. They have a tendency to lose an outer shell electron, resulting in cations with a charge of +1. (monovalent ions), they are not found in their pure form because of the same reason.
  4. Alkali metals react with oxygen in the air and lose their lustrous appearance. They form oxides when they react with oxygen.
  5. All halogens react violently with alkali metals, forming solid ionic halides with a distinct crystal structure.
  6. Sulfides are formed when alkali metals react with elemental sulfur directly, resulting in a variety of sulfides.

Hydrogen:

  1. Hydrogen, with an atomic number of 1, is the smallest and lightest among all the other elements. It is most commonly found as a gas, and it is colorless, odorless, and combustible.
  2. It shows some chemical similarities with the group 1It has an electronic configuration that is similar to group 1 elements.
  3. It rapidly loses an electron to generate an H+ion, which has electropositive properties similar to group 1 elements.
  4. It has the same oxidation state as alkali, i.e. +1 oxidation state.
  5. Hydrogen, like alkali metals, is also a powerful reducing agent and produces binary compounds with electronegative elements that are similar to group 1 elements. Example halides, sulfides, oxides.

Therefore, like alkali metals Hydrogen also forms oxides, halides, and sulfides.
