Answer:
Subshell 2p is being filled moving from boron to neon.
Explanation:
As we move from Boron to neon six elements are covered. Boron is present in group 13 , carbon is present in group 14, nitrogen is present in group 15, oxygen is present in group 16, fluorine is present in group 17 and neon is present in group 18.
The atomic number of boron is five. Electronic configuration is given below:
B₅ = 1s² 2s² 2p¹
The atomic number of carbon is six. Electronic configuration is given below:
C₆ = 1s² 2s² 2p²
The atomic number of nitrogen is seven. Electronic configuration is given below:
N₇ = 1s² 2s² 2p³
The atomic number of oxygen is eight. Electronic configuration is given below:
O₈ = 1s² 2s² 2p⁴
The atomic number of fluorine is nine. Electronic configuration is given below:
F₉ = 1s² 2s² 2p⁵
The atomic number of neon is ten. Electronic configuration is given below:
Ne₁₀ = 1s² 2s² 2p⁶
we can see in each electronic configuration 2p subshell is being filled.
