Question

protons, neutrons, and electrons for an atom. i can determine the number of neutrons when given the mass number, or the mass number and neutrons, for any isotope. i can write the hyphen notation for any isotope given protons, neutrons, and electrons and find protons, neutrons, and electrons for an atom. here are three isotopes of an element: $_6^{12}c$ $_6^{13}c$ $_6^{14}c$ 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 e. how many protons and neutrons are in f. how many protons and neutrons are in

Explanation:

Step1: Identify the element

The symbol C represents carbon.

Step2: Recall atomic number concept

The atomic number is the number of protons in an atom and is unique to each element. For carbon - 6 is the atomic number.

Step3: Recall mass number concept

The mass number is the sum of protons and neutrons in an atom. 12, 13, 14 are the mass numbers of the carbon isotopes.

Step4: Calculate protons and neutrons for \(_{6}^{12}C\)

Protons = atomic number = 6. Neutrons = mass number - protons = 12 - 6 = 6.

Step5: Calculate protons and neutrons for \(_{6}^{13}C\)

Protons = 6. Neutrons = 13 - 6 = 7.

Step6: Calculate protons and neutrons for \(_{6}^{14}C\)

Protons = 6. Neutrons = 14 - 6 = 8.

Answer:

a. Carbon
b. Atomic number
c. Mass numbers
d. Protons: 6, Neutrons: 6
e. Protons: 6, Neutrons: 7
f. Protons: 6, Neutrons: 8
