30 POINTS What were their experiences in life that led to their interest in science and the study of the atom? (this is for Erwin Schrodinger please add where you got the info!)

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

If two atoms are bonded to a central atom with no lone pairs, how will they be arranged
