Question

complete the table.

iodine
arsenic
nitrogen
sulfur
tin

Explanation:

Step1: Recall atomic structure relationships

• Atomic number = number of protons.
• Mass number = number of protons + number of neutrons.
• For a neutral atom, number of protons = number of electrons. For ions, charge = protons - electrons.

Step2: Analyze each row

• Iodine:
• Atomic number = 53 (given), so protons = 53.
• Mass number = protons + neutrons = 53 + 76 = 129 (error in original mass number 127).
• Charge = 1 - means electrons = protons + 1 = 53 + 1 = 54.
• Arsenic:
• Symbol is As (not Ar, Ar is Argon).
• Charge = protons - electrons = 33 - 36 = - 3.
• Nitrogen:
• Symbol is N (correct).
• Atomic number = 7 (correct).
• Protons = 7 (correct).
• Neutrons = mass number - protons = 14 - 7 = 7 (correct).
• Electrons = 7 (neutral, correct).
• Sulfur:
• Atomic number = 16 (protons = 16).
• Mass number = protons + neutrons = 16 + 18 = 34 (error in original mass number 33).
• Charge = protons - electrons = 16 - 18 = - 2 (error in original charge 0).
• Tin:
• Protons = atomic number = 50.
• Neutrons = mass number - protons = 119 - 50 = 69.
• Charge = 4 + means electrons = protons - 4 = 50 - 4 = 46.

Answer:

Element	Symbol	Atomic number	Mass number	Protons	Neutrons	Electrons	Charge
Arsenic	As	33	77	33	36	36	- 3
Nitrogen	N	7	14	7	7	7	0
Sulfur	S	16	34	16	18	18	- 2
Tin	Sn	50	119	50	69	46	4 +
