Question

1. fill in the following table. be careful, it contains atoms, ions and isotopes.

isotopic notation	atomic #	mass #	# of protons	# of electrons	# of neutrons	net charge	cation / anion
$^{108}_{47}ag^{1 + }$				46
			30		35	0
	55	133				3+
$^{31}_{15}p^{3 - }$

Explanation:

Step1: Recall atomic number properties

The atomic number is equal to the number of protons. Given atomic number = 13, so number of protons = 13. Mass number = number of protons+number of neutrons. So mass number = 13 + 15=28. Since number of protons = number of electrons = 13, net charge = 0 and it's a neutral atom. Isotopic notation: $^{28}_{13}Al$.

Step2: Analyze silver - ion

For $^{108}_{47}Ag^{1 + }$, atomic number = 47, so number of protons = 47. Mass number = 108. Number of electrons = 46 (as it has a + 1 charge). Number of neutrons=mass number - number of protons = 108 - 47 = 61. Net charge = + 1 and it's a cation.

Step3: Determine neutral - atom details

If number of protons = 30, atomic number = 30. Element is zinc. Mass number = number of protons+number of neutrons = 30 + 35 = 65. Since net charge = 0, number of electrons = 30. Isotopic notation: $^{65}_{30}Zn$.

Step4: Analyze ion with 3+ charge

Atomic number = 55, so number of protons = 55. Mass number = 133. Number of neutrons = 133 - 55 = 78. Since net charge = 3 +, number of electrons = 55 - 3=52. It's a cation. Isotopic notation: $^{133}_{55}Cs^{3 + }$.

Step5: Analyze phosphorus - ion

For $^{31}_{15}P^{3 - }$, atomic number = 15, so number of protons = 15. Mass number = 31. Number of neutrons = 31 - 15 = 16. Since it has a - 3 charge, number of electrons = 15+3 = 18. Net charge=-3 and it's an anion.

Isotopic Notation	Atomic #	Mass #	# of Protons	# of Electrons	# of Neutrons	Net Charge	Cation / Anion
$^{108}_{47}Ag^{1 + }$	47	108	47	46	61	+ 1	Cation
$^{65}_{30}Zn$	30	65	30	30	35	0	Neutral
$^{133}_{55}Cs^{3 + }$	55	133	55	52	78	+ 3	Cation
$^{31}_{15}P^{3 - }$	15	31	15	18	16	- 3	Anion
