6 sep use mathematics complete the table by identifying the atomic number and mass number for each atom and then using those data to determine the numbers of protons, neutrons, and electrons. composition of atoms atom atomic number mass number protons electrons neutr ₂₃₁₁na 11 23 ₃₂₁₆s 16 32 silver - 108 47 108 gold - 197 79 196.967

Explanation:

Step1: Recall atomic - particle relationships

The atomic number ($Z$) is equal to the number of protons and for a neutral atom, the number of electrons. The mass number ($A$) is the sum of protons and neutrons. Neutrons ($n$) = Mass number - Atomic number.

Step2: For $\ce{^{23}_{11}Na}$

Protons = Atomic number = 11. Electrons = Protons = 11 (since it's neutral). Neutrons = Mass number - Atomic number = 23 - 11 = 12.

Step3: For $\ce{^{32}_{16}S}$

Protons = Atomic number = 16. Electrons = Protons = 16 (since it's neutral). Neutrons = Mass number - Atomic number = 32 - 16 = 16.

Step4: For silver - 108

Protons = Atomic number = 47. Electrons = Protons = 47 (since it's neutral). Neutrons = Mass number - Atomic number = 108 - 47 = 61.

Step5: For gold - 197

Protons = Atomic number = 79. Electrons = Protons = 79 (since it's neutral). Neutrons = Mass number - Atomic number = 196.967 - 79≈118 (rounding for whole - number of neutrons in this context).

Answer:

Atom	Atomic number	Mass number	Protons	Electrons	Neutrons
$\ce{^{32}_{16}S}$	16	32	16	16	16
silver - 108	47	108	47	47	61
gold - 197	79	196.967	79	79	118
