100 square each for newtons of force
<span>Answer: O₃
</span><span />
<span>Explanation:
</span>
<span /><span /><span>
The term isoelectronic means same number of electrons.
</span><span />
<span>Then you need to count the number of electrons in the given species NO₂⁻.
</span><span />
<span>You have to count the number of electrons of N (nitrogen) atoms, the number of electrons of two O (oxygen) atoms, and the adjust for the negative charge of the ions.
</span><span>The atomic number of N is 7, meaning that each atom has 7 protons and 7 electrons.</span>
<span /><span>
The atomic number of O is 8, meaning that each atom has 8 protons and 8 electrons.
</span><span />
<span>The negative charge of the ion means that it has one extra electron, which is the responsible for the negative charge.
</span><span />
<span>Therefore the total number of electrons of the ion NO₂⁻ is 7 + 2 (8) + 1 = 24.
</span><span />
<span>Note that that 24 = 3 x 8, so 24 is the number of electrons in 3 atoms of oxygen.
</span><span />
<span>The moleucle O₃ is an allotrope of the oxygen. (an allotrope is a a form of an element with different structure and physical properties in the same physical state).
</span><span />
<span>Therefore, the allotrope of oxygen isoelectronic with NO₂⁻ is O₃ (ozone)</span>
The line in between indicates that there is a single bond connecting the two carbon atoms. Atoms can be bonded via single bond, double bond and a triple bond. Among the three, the single bond is the weakest, but it allows for more atoms to connect to it because it leaves 3 more pairs available for bonding.
So in summary, among all the bonds that was given, a c-c bond is the weakest and the longest.
