1. here are three isotopes of an element: \n a. the element is: ____________ \n b. the numbers 12, 13, and 14 refer to the ____________ \n c. in the first isotope there are ______ p+ and ______ n. \n d. in the second isotope there are ______ p+ and ______ n. \n e. in the third isotope there are ______ p+ and ______ n. \n 2. complete the following chart:
Answer
Explanation:
Step1: Identify the element
The atomic number (sub - script) is 6 for all isotopes. Atomic number determines the element, and the element with atomic number 6 is carbon.
Step2: Identify the meaning of the numbers
The numbers 12, 13, and 14 are the mass numbers. Mass number = number of protons + number of neutrons.
Step3: Determine protons and neutrons for each isotope
For an isotope, the number of protons is equal to the atomic number. The number of neutrons = mass number - number of protons.
- For $^{12}_{6}C$: Protons (P+) = 6, Neutrons (N) = 12 - 6=6.
- For $^{13}_{6}C$: Protons (P+) = 6, Neutrons (N) = 13 - 6 = 7.
- For $^{14}_{6}C$: Protons (P+) = 6, Neutrons (N) = 14 - 6 = 8.
Answer:
a. Carbon b. Mass numbers c. 6, 6 d. 6, 7 e. 6, 8
