consider the electron configuration.\nwhich element has this electron configuration?\nastatine\nbromine\nchlorine\nfluorine
Answer
Explanation:
Step1: Count 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, $2 + 2+6 + 2+5=17$.
