Selenium: [Ar]3d104s24p4
Phosphorus: [Ne]3s23p3
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
P3- ion or phosphide ion as the same electron configuration as the noble gas, argon
Sulfurs noble gas core electronic configuration is [Ne]3s2 3p4
"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of phosphorus will be [Ne]3s23p3
The noble gas electron configuration of Phosphorus is [Ne] 3s2 3p3

Yes it will as P-3 ion will have the same electron configuration of the noble gas, argon.
The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
