Respuesta :
The 5 electrons are present in the valence shell so group number 15 or VA or 5A electronic configuration ns^2 np^3, 4 electrons are present in the valence shell so the group number 14 or 1VA or 4 A electronic configuration ns^2 np^2.
What is an electron ?
The negatively charged components of an atom are known as electrons. All of an atom's electrons combine to form a negative charge that counteracts the positive charge of the protons in the atomic nucleus. In comparison to all the other components of the atom, electrons are quite tiny.
What is an electron configuration?
The placement of electrons in orbitals around a nuclear nucleus is known as electronic configuration, also known as electronic structure or electron configuration.
A, 5 electrons are present in the valence shell so group number 15 or VA or 5A electronic configuration ns^2 np^3.
B, 4 electrons are present in the valence shell so the group number 14 or 1VA or 4 A electronic configuration ns^2 np^2
Therefore, 5 electrons are present in the valence shell so group number 15 or VA or 5A electronic configuration ns^2 np^3, 4 electrons are present in the valence shell so the group number 14 or 1VA or 4 A electronic configuration ns^2 np^2.
