Match the entries in column I with the entries in column II. Elements

1.	Match the entries in column I with the entries in column II. ElementsElectronic configuration(i) C−4 is highly unstable because(a) It would be difficult for carbon with six protons in its nucleus to hold on just two electrons.(ii) C+4 is achieved by(b) gaining four electrons to its outermost orbit(iii) C+4 is highly unstable because(c) losing four valence electrons(iv) C−4 is achieved by(d) It is difficult for the nucleus with six protons to hold on ten electrons, i.e. four extra electrons
Answer» Match the entries in column I with the entries in column II. $\begin{matrix} Elements & Electronic configuration (i) C^{- 4} is highly unstable because & (a) It would be difficult for carbon with six protons in its nucleus to hold on just two electrons. (ii) C^{+ 4} is achieved by & (b) gaining four electrons to its outermost orbit (iii) C^{+ 4} is highly unstable because & (c) losing four valence electrons (iv) C^{- 4} is achieved by & (d) It is difficult for the nucleus with six protons to hold on ten electrons, i.e. four extra electrons \end{matrix}$
