F with 9 electrons gains electron to form F- here,nw with 10 electrons lyk dt of neon.
isoelectronic refers to two atoms,ions,or molecules that have thesame atomic structure and thesame number of valance electron on the other way isoelectronic may define as the element that have thesame electronic configuration therefore from the question only fluorine has thesame electronic configuration neon for exampe 1s2,2s2,2p5 for fluorine and neon are 1s2,2s2,2p6 this means neon and florine has thesame electronic configuration
elements go into rxn to attain stability and an octet configuration lyk d noble gases,so F in rxn forms F- after receiving electron and nw stable with a configuration lyk dat of noble gases
