Question

Identify from the following the isoelectronic species Ne, O2-,Na+,OR Are,Cl2,k+

Answer 1

Explanation:

Note:the negative sign indicates that they are gaining electrons

and positive sign indicates that they are loosing electrons

so according to the above imformation

Ne--->atomic number---->10

O^2------->atomic number--->8--->gaining

two electrons as the -ve sign

indicates ,we have 8+2=10electrons

Na+-------->atmic number---->11

losing 1 electrons now we have 10electrons

Cl2--------->atmic number------>17

K+---------->atmic number------>19

loosing 1 electron as the +ve sign indicates so we have 18electrons

The isolectric species are neon(ne) or

oxygen(o2)

because both have same number of electrons
