the table below gives the numbers of protons, electrons, and neutrons in four atoms.\n|atom|number of protons|number of neutrons|number of electrons|\n|----|----|----|----|\n|1|9|8|9|\n|2|9|9|8|\n|3|9|9|10|\n|4|9|10|9|\nbased on the table, which atom has a charge of - 1?\n1\n2\n3\n4
Answer
Explanation:
Step1: Recall charge - calculation formula
The charge of an atom is calculated as Charge = Number of protons - Number of electrons.
Step2: Calculate charge for Atom 1
For Atom 1, Number of protons = 9, Number of electrons = 9. Charge = 9 - 9 = 0.
Step3: Calculate charge for Atom 2
For Atom 2, Number of protons = 9, Number of electrons = 8. Charge = 9 - 8 = + 1.
Step4: Calculate charge for Atom 3
For Atom 3, Number of protons = 9, Number of electrons = 10. Charge = 9 - 10=-1.
Step5: Calculate charge for Atom 4
For Atom 4, Number of protons = 9, Number of electrons = 9. Charge = 9 - 9 = 0.
