consider the electron configuration. 1s ↑↓ 2s ↑↓ 2p ↑↓↑↓↑↓ 3s ↑↓ 3p ↑↓↑↓↑ which element has this electron configuration? astatine bromine chlorine fluorine
Answer
Explanation:
Step1: Count the total electrons
Count the number of electrons in each orbital. 1s has 2 electrons, 2s has 2 electrons, 2p has 6 electrons, 3s has 2 electrons and 3p has 5 electrons. So, $2 + 2+6 + 2+5=17$.
Answer:
chlorine
