Write the condensed electron configurations for the following atoms and indicate how many unpaired electrons each has. for Ca and Y

for Ca i got [Ar] 4s2 but it got cuonted wrong

  • chem -

    I suspect it was counted wrong because you didn't say how many unpaired electrons. There are zero in Ca.
