electron configuration and noble gas notation\nthe orbital diagram below represents which element?\no magnesium\no silicon\no phosphorus
Answer
Explanation:
Step1: Count electrons in each orbital
1s has 2 electrons, 2s has 2 electrons, 2p has 6 electrons, 3s has 2 electrons, 3p has 3 electrons.
Step2: Calculate total number of electrons
$2 + 2+6 + 2+3=15$ electrons.
Step3: Identify element by atomic number
The atomic number is equal to the number of electrons. Phosphorus has an atomic number of 15.
Answer:
phosphorus
