Question
Write the shorthand electron configurations for the following atoms. Enter full electron configuration in order electrons fill the subshells with number of electrons in the subshells in parentheses. For example, write the electron configuration for Li as [He]2s(1). The answer is case sensitive. Write the shorthand electron configurations for the following atoms. Enter full electron configuration in order electrons fill the subshells with number of electrons in the subshells in parentheses. For example, write the electron configuration for Li as [He]2s(1). The answer is case sensitive. Al, Se, Ba, Sb, Gd Write the shorthand electron configurations for the following atoms. Enter full electron configuration in order electrons fill the subshells with number of electrons in the subshells in parentheses. For example, write the electron configuration for Li as [He]2s(1). The answer is case sensitive.Explanation / Answer
Al = 1s(2) 2s(2) 2p(6) 3s(2) 3p(1)
= [Ne] 3s(2) 3p(1)
Se = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(4)
= [Ne] 4s(2) 3d(10) 4p(4)
Ba = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(6) 5s(2) 4d(10) 5p(6) 6s(2)
= [Xe] 6s(2)
Sb = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(6) 5s(2) 4d(10) 5p(3)
= [Kr] 5s(2) 4d(10) 5p(3)
Gd = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(6) 5s(2) 4d(10) 5p(6) 6s(2) 4f(8)
= [Xe] 6s(2) 4f(8)
