1. Write electrоn cоnfigurаtiоn of Y2+ by filling number of electrons in eаch orbitаl. Write orbital symbol first, followed by number of electrons in [ ] (e.g., electron configuration for O would be 1s[2]2s[2]2p[4]). Condensed form of electron configuration is accepted. 2. How many unpaired electrons does Y2+ have ? (must have correct electron configuration above to get credit)
