Question

1. in each of the following statements, you are given a pair of elements and important information about each in the space provided. determine if the pair of elements is a set of isotopes or different elements. indicate your answer a. element d has 6 protons and 7 neutrons. b. element f has 7 protons and 7 neutrons. c. element j has 27 protons and 32 neutrons. d. element l has 27 protons and 33 neutrons. e. 6 14x and 7 14x

Explanation:

Step1: Recall the definition of isotopes

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons.

Step2: Analyze pair a

Element D has 6 protons and 7 neutrons, Element F has 7 protons and 7 neutrons. Since they have different numbers of protons, they are different elements.

Step3: Analyze pair b

Element J has 27 protons and 32 neutrons, Element L has 27 protons and 33 neutrons. They have the same number of protons (27) and different numbers of neutrons, so they are isotopes.

Step4: Analyze pair e

The notation $_6^{14}X$ and $_7^{14}X$ represents elements with 6 and 7 protons respectively. Since they have different numbers of protons, they are different elements.

Answer:

a. Different elements
b. Isotopes
e. Different elements
