Jawaban:

begin mathsize 14px style Isoelektronik comma space artinya space memiliki space jumlah space elektron space yang space sama. space  Ne presubscript 10 space memiliki space 10 space elektron comma space jadi space straight X to the power of plus 3 end exponent space juga space memiliki space 10 space elektron. space  Tanda space plus 3 comma space artinya space telah space melepas space 3 space elektron comma space sehingga space  atom space straight X space sendiri space memiiki space 13 space elektron.  Sehingga space konfigurasi space dari space subscript 13 straight X space adalah space colon space  1 straight s squared space 2 straight s squared space 2 straight p to the power of 6 space 3 straight s squared space 3 straight p to the power of 1 end style
