Answer:
Ii is the circuit overload
Explanation:
Answer:
Phosphorus
Explanation:
In given diagram there are 15 electrons are present. Which means it is orbital diagram of phosphorus.
The atomic number of phosphorus = 15
Number of electrons = 15
Electronic configuration of phosphorus:
P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³
All other options are incorrect because:
Calcium have 20 electrons.
Electronic configuration of Ca:
Ca₂₀ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
Hydrogen have one electron.
Electronic configuration of H.
H₁ = 1s¹
Magnesium have 12 electrons:
Electronic configuration of Mg:
Mg₁₂ = 1s² 2s² 2p⁶ 3s²
