Element is


\boxed{\sf {}^(27)Al_(13)}

  • Atomic number=13
  • Mass number=27


\\ \sf\longmapsto No\:of\:Protons=Atomic \:Number=13

And


\\ \sf\longmapsto No\:of\:Neutrons=Mass\:number-Atomic\:Number


\\ \sf\longmapsto No\:of\:Neutrons=27-13


\\ \sf\longmapsto No\:of\:Neutrons=14

And


\\ \sf\longmapsto No\:of\:electrons=No\:of\:Protons=13
