Question

what is diagonal relationship? explain it in case of boron (B) and silicon (Si)?​

Answer 1

Answer:

Explanation:

Diagonal relationship is a relationship between boron and silicon. The behaviour of Boron in its group is small and the size is small and their availability as it also resembles the silicon that the silicon is the second number of the next higher group. Moreover both of the Boron and silicon are the non-metals and these elements exists in allotropic form.

Answer 2

Diagonal relationship: in period table we often find elements of adjacent groups with a period down exhibits same properties.

• if we move from left to right in a period progressively atomic radii and basic nature decreases; covalency and electroneagitivity increases.
• if we move down the group atomic radii, basic nature, ionic nature increases and electroneagitivity decreases.
• The elements which are diagonal in in second period; first group, and second group cancel out those properties and show more similarities than differences.

Boron(B) and Silicon(Si): Boron and silicon have similar chemical properties like

• Both are semiconductors.
• They both on reaction with halogens form Halides.
• Both of these halides in water form acidic oxides.
