Answer:-
Ca-Cl
Explanation:-
The more the difference in electronegativity more the polar bond.
In case of Ca-Cl the difference = 3.16 - 1= 2.16
It is more than all the other combinations given.
Hence Ca-Cl is the most polar covalent bond.
Answer: If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.
Explanation:
<span>By far the most common isotope of carbon is carbon-12(<span>12C</span>), which contains six neutrons in addition to its six protons. The next heaviest carbon isotope, carbon-13 (<span>13C</span>), has seven neutrons. Both <span>12C</span> and <span>13C</span> are called stable isotopes since they do not decay into other forms or elements over time.</span>
