Question

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
$_{11}^{23}na$ 11 22.990
$_{16}^{32}s$ 16 32.066
silver - 108 47 107.868

Explanation:

Step1: Recall atomic - related rules

The atomic number is equal to the number of protons and for a neutral atom, the number of electrons is equal to the number of protons. The number of neutrons is calculated as mass number - atomic number.

Step2: For \(_{11}^{23}Na\)

Atomic number \(Z = 11\), mass number \(A=22.990\approx23\). Protons \(= 11\), electrons \( = 11\), neutrons \(=A - Z=23 - 11 = 12\).

Step3: For \(_{16}^{32}S\)

Atomic number \(Z = 16\), mass number \(A = 32.066\approx32\). Protons \(=16\), electrons \(=16\), neutrons \(=A - Z=32 - 16 = 16\).

Step4: For silver - 108

Atomic number \(Z = 47\), mass number \(A = 107.868\approx108\). Protons \(=47\), electrons \(=47\), neutrons \(=A - Z=108 - 47 = 61\).

Answer:

Atom	Atomic number	Mass number	Protons	Electrons	Neutrons
\(_{16}^{32}S\)	16	32	16	16	16
silver - 108	47	108	47	47	61
