Question

Indicate which of the given electronic configurations are true ground state configurations for the respective atoms and which are false.
(Take care! There are some exceptions to the simple rules.)

1. true false  Au [Xe]4f¹⁴5d⁹6s²

2. true false  Hg [Xe]4f¹⁴5d¹⁰6s²

3. true false  Si 1s²2s²2p⁶3d²3s²

4. true false  F 1s²2s²2p⁵

5. true false  Cr [Ar]3d⁵4s¹

Answer 1

first find the atomic number and electrons of each atom and then write the correct electronic configuration and find true or false as follows
