Identify an element on the periodic table that is chemically similar to boron (b)

The element which is chemically similar to boron is Siicon.

Explanation:

Boron is the 5th element of the periodic table and lies in the 2nd period in the periodic table.

Boron pairs up with silicon to show a diagonal relationship. This relationship exists between few pairs of the elements present in period 2 and period 3 till atomic number 20.

In this relationship, the chemical properties of the two elements seem to be same.

Boron and silicon both are semiconductor, forms halides which are hydrolyzed in water and both have acidic oxides.

Hence, the element which is chemically similar to boron is Silicon.

yes it is balanced

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
