(a)
Interpretation:
Interpret total number of valence electron in H2S
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bond formed between two atoms by sharing of electrons is known as covalent bond. A single
Total number of valence electron can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule such as:
For HxOy
Total number of valence electron = number of H (valence electron of H) + number of O (valence electron of O)
(b)
Interpretation:
Interpret total number of valence electron in I2
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bond formed between two atoms by sharing of electrons is known as covalent bond. A single chemical bond is formed by sharing of 2 electrons while double bond is formed by sharing of 4 and triple bond is formed by sharing of 6 electrons.
Total number of valence electron can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule such as:
For HxOy
Total number of valence electron = number of H (valence electron of H) + number of O (valence electron of O)
