Which of these elements has two electrons in its outer p orbitals?

helium (he)

barium (ba)

nitrogen (n)

silicon (si)

sulfur (s)

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,

Element = Barium

Atomic number = Number of electrons = 56

The electronic configuration will be,

Element = Nitrogen

Atomic number = Number of electrons = 7

The electronic configuration will be,

Element = Silicon

Atomic number = Number of electrons = 14

The electronic configuration will be,

Element = Sulfur

Atomic number = Number of electrons = 16

The electronic configuration will be,

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)
