प्रश्न
An element A has 1 electron in its first shell. It combines with element B having 7 electrons in its third shell. What type of bond is formed?
उत्तर
Element A with 1 electron in its first shell is hydrogen, and element B with 7 electrons in its third shell is chlorine.
So, a single covalent bond is formed between hydrogen and chlorine by sharing one pair of electrons.
