Textbook Problem

One of the indicators used was CO2 labeled with the radioactive carbon isotope carbon-14. The researchers detected that H2CO3 was moving through the rock matrix by measuring the radioactivity of the water at the detection well. Give the number of protons, electrons, and neutrons in a carbon-14 atom.

Interpretation Introduction

Interpretation:

The number of protons, electrons and neutrons in C14 should be identified.

Concept introduction:

Isotopes:

The molecule has same atomic number but different mass number is called isotopes.

The atomic number = number of protons

Atomic weight = total number protons and neutrons.

Explanation

Carbon-14 has a half-life of 5,730 years.  14C is used to determine the ages of artifacts such as pieces of wood, coral skeletons and etc. is called as radiocarbon dating.

Carbon-14 is an isotope of carbon atoms has 6 protons in their nucleus...
