Question

1. here are three isotopes of an element: (^{12}_6c), (^{13}_6c), (^{14}_6c). a. the element is: b. the number 6 refers to the c. the numbers 12, 13, and 14 refer to the d. how many protons and neutrons are in the first isotope? e. how many protons and neutrons are in the second isotope? f. how many protons and neutrons are in the third isotope? 2. complete the following charts. hyphen notation atomic # mass # # of protons # of neutrons # of electrons

Explanation:

Step1: Recall isotope - proton - neutron relationship

Isotopes of an element have the same number of protons. The atomic number is equal to the number of protons. For carbon, the atomic number is 6, so all carbon isotopes have 6 protons.

Step2: Calculate neutrons for first isotope

The mass number is the sum of protons and neutrons. For the first isotope with mass number 12, if the number of protons $p = 6$, then the number of neutrons $n=12 - 6=6$.

Step3: Calculate neutrons for second isotope

For the second isotope with mass number 13, since $p = 6$, then $n = 13 - 6=7$.

Step4: Calculate neutrons for third isotope

For the third isotope with mass number 14, since $p = 6$, then $n=14 - 6 = 8$.

Step5: Electron - proton relationship

In a neutral atom, the number of electrons is equal to the number of protons. So for all these carbon isotopes, the number of electrons is 6.

Isotope	Atomic #	Mass #	# of protons	# of neutrons	# of electrons
$^{13}C$	6	13	6	7	6
$^{14}C$	6	14	6	8	6

Answer:

Isotope	Atomic #	Mass #	# of protons	# of neutrons	# of electrons
$^{13}C$	6	13	6	7	6
$^{14}C$	6	14	6	8	6
