Answer:
The cations are 
Explanation:
Atomic number = Number of protons present in the nucleus of an atom of the element
Number of protons =14
Atomic number of an element will be 14.
The name of the element with 14 atomic number is silicon. It has equal number of electrons. Since an atom is a neutral species.
After loosing electrons atom gain positive charge.
![[Si]=1s^22s^22p^63s^23p^2](https://tex.z-dn.net/?f=%5BSi%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E2)
After losing an electron is becomes 
![[Si^+]=1s^22s^22p^63s^23p^1](https://tex.z-dn.net/?f=%5BSi%5E%2B%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E1)
After losing 2 electron is becomes 
![[Si^{2+}]=1s^22s^22p^63s^23p^0](https://tex.z-dn.net/?f=%5BSi%5E%7B2%2B%7D%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E0)
After losing 3 electron is becomes 
![[Si^{3+}]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BSi%5E%7B3%2B%7D%5D%3D1s%5E22s%5E22p%5E6)
