Problem 55E

The amount of carbon-14 in ancient artifacts and fossils is often used to establish their age. Determine the number of protons and the number of neutrons in a carbon-14 isotope and write its symbol in the form

Step-by-Step Solution:
Step 1 of 3

Solution : Let’s consider the 1st set of data : The given symbol is Co. Cobalt is the chemical name of symbol Co. It has an atomic number of 27. Atomic number indicates the number of protons and electrons. So there are 27 rotons and electrons. But there is an charge of 3+ which indicates there is loss of 3 electrons, Hence number of electrons here is 4. Mass number is given as 59. To find the number of neutrons, we subtract the number of protons from the mass number as mass number is the sum of number of protons and neutrons. Therefore, Number of neutrons = 59- 27 = 3 2. Let’s consider the 2nd set of data : Number of protons is given as 34. It indicates the element’s atomic number is 34. Element with atomic number 34 is Selenium(Se). Number of electrons is given as 36. This indicates there is gain of 2 electrons as in neutral state number of protons and electrons are equal and hence the element has a charge of 2-. Mass number is the sum of protons and neutrons....
