Write the symbols of three isotopes of carbon.

Isotopes:

• These are the substance of chemical elements that contains the same number of protons and electrons, but having different number of neutrons.
• Isotopes differ in the number of neutrons.
• For example, carbon-14 (₆C¹⁴), carbon-13 (₆C¹³), and carbon-12 ( ₆C¹²) are all symbols of isotopes of carbon.
• Number of neutrons is calculated subtracting atomic mass from atomic number)
• ₆C¹⁴ ( Number of neutrons= 14-6=8), ₆C¹³ ( Number of neutrons= 13-6 = 7), ₆C¹² (Number of neutrons= 12-6= 6)
