Can someone please help me with these questions please?
1.Write the ground state electron configuration for an arsenic atom, showing the number of electrons in each subshell.
2.Give one permissible set of four quantum numbers for each of the outermost electrons in a single As atom when it is in its ground state.
3.Is an isolated arsenic atom in the ground state paramagnetic or diamagnetic? Explain briefly.
4.Explain how the electron configuration of the arsenic atom in the ground state is consistent with the existence of the following known compounds: Na3As, AsCl3, and AsF5.
Thank you very much

1. Electronic configuration is right there: http://www.webqc.org/periodictable-Arsenic-As.htmlKle wrote:Can someone please help me with these questions please?
