Silicon (si) has two electrons in its outer p orbitals.
Explanation:
For the element of SILICON, you previously know that the atomic number shows the number of electrons. That indicates there are 14 electrons in a silicon atom. Looking at the design, you can see there are two particles in shell one, eight in shell two, and four in shell three. Si which is 4 elements from the left side of the table,first 2 electrons are s orbitals when next two electrons go to Si
Answer : The correct option is, Silicon (Si)
Explanation :
Element = Helium
Atomic number = Number of electrons = 2
The electronic configuration will be, [tex]1s^2[/tex]
Element = Barium
Atomic number = Number of electrons = 56
The electronic configuration will be, [tex]1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^24d^{10}5p^66s^2[/tex]
Element = Nitrogen
Atomic number = Number of electrons = 7
The electronic configuration will be, [tex]1s^22s^22p^3[/tex]
Element = Silicon
Atomic number = Number of electrons = 14
The electronic configuration will be, [tex]1s^22s^22p^63s^23p^2[/tex]
Element = Sulfur
Atomic number = Number of electrons = 16
The electronic configuration will be, [tex]1s^22s^22p^63s^23p^4[/tex]
From the electronic configurations, we conclude that the element silicon has two electrons in its valence 'p' orbital or outermost 'p' orbitals.
Hence, the correct option is, Silicon (Si)
