Question

Here are three isotopes of an element:

6_C^12
6_C^13
6_C^14
The element is: ________ .

A) Nitrogen
B) Carbon
C) Oxygen
D) Hydrogen

Answer 1

The three isotopes listed, with atomic number 6, are all isotopes of carbon, which include carbon-12, carbon-13, and carbon-14.

Step-by-step explanation:

The three isotopes mentioned in the question, 6_C^12, 6_C^13, and 6_C^14, all have the atomic number 6, which corresponds to the element carbon. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. In this case, the isotopes represent carbon-12 (1²C), carbon-13 (1³C), and carbon-14 (14C). Carbon-12, the most abundant isotope, has 6 protons and 6 neutrons. Carbon-13 has 6 protons and 7 neutrons, while Carbon-14 has 6 protons and 8 neutrons. Hence, the answer to the question is B) Carbon.
