Which compound contains both ionic and covalent bonds?
slava [35]
<span>Answer is </span>(3) - Sodium Nitrate.<span>

</span>Normally ionic bonds can be seen between metals and non-metals while covalent bonds present between non-metals. Another thing that determines the bond nature is electronegativity value of the atoms. If the electronegativity difference is high, then that bond tends to be an ionic bond.<span>
 
</span><span>Sodium nitrate consists of </span>Na⁺<span> and </span>NO₃⁻ ions. Hence, the bond between Na⁺ and NO₃⁻<span> is an </span>ionic bond. <span><span>

NO</span>₃⁻ </span><span>is made from </span>N <span>and </span>O<span>. Both are </span>non-metallic atoms. <span>The </span>electronegativities <span>of </span>N <span>and </span>O <span>are </span>3.0 <span>and </span>3.5 <span>respectively. Hence, there is </span>no big difference between electronegativity values (3.5 - 3.0 = 0.5<span>). Hence, the bond between N and O is a </span><span>covalent bond. </span>
