examine the data table below and use the data to answer questions 5 - 9. note that the atom letters are random and not associated with atomic symbols for the elements.\n\n| atom | protons | neutrons | electrons |\n| ---- | ---- | ---- | ---- |\n| a | 20 | 20 | 18 |\n| b | 4 | 3 | 3 |\n| c | 20 | 18 | 20 |\n| d | 73 | 110 | 71 |\n| e | 17 | 18 | 18 |\n\n5. which atoms are isotopes of the same element?\na) atom a and atom e\nb) atom a and atom c\nc) atom c and atom e\nd) no isotopes are shown in this table.\n\n6. examine atom b. choose the appropriate identity:\na) lithium - 6\nb) lithium - 7\nc) beryllium - 6\nd) beryllium - 7\n\nfor each of the questions below, list/bubble any and all atoms (a - e) that apply. this means you may have more than one answer for each question.\n\n7. which atom(s) have a net negative charge?\n8. which atom(s) are neutral in charge?
Answer
Explanation:
Step1: Recall isotope definition
Isotopes are atoms of the same element with different numbers of neutrons but the same number of protons. Atom A has 20 protons and atom C has 20 protons with different numbers of neutrons.
Step2: Recall atomic identity rule
The atomic number is equal to the number of protons. Atom B has 4 protons, and beryllium has an atomic number of 4. The mass - number is the sum of protons and neutrons, so for atom B, mass - number = 4 + 3=7.
Step3: Determine net charge
Net charge = number of protons - number of electrons. For atom A: 20 - 18 = + 2; for atom B: 4 - 3 = + 1; for atom C: 20 - 20 = 0; for atom D: 73-71 = + 2; for atom E: 17 - 18=-1.
Step4: Identify neutral atoms
Neutral atoms have equal number of protons and electrons. Atom C has 20 protons and 20 electrons, so it is neutral.
Answer:
- b) Atom A and atom C
- d) Beryllium - 7
- E
- C
