Question

part iii. fill in the isotope names and any missing information on the chart. use your periodic table and the information provided. assume all atoms are neutral.

of protons

29

of neutrons

17
15

of electrons

of protons

32

of neutrons

30
32

of electrons

Explanation:

Step1: Recall atomic - related concepts

In a neutral atom, the number of protons = the number of electrons. The mass number (A) = number of protons (Z)+ number of neutrons (N).

Step2: First table

Since the number of protons is 29, the element is copper (Cu) from the periodic table. The number of electrons is also 29 as the atom is neutral. The mass number A = 29 + 17=46. The isotope name is copper - 46.

Step3: Second table

For the first row with 32 protons, the element is germanium (Ge). Since it is neutral, the number of electrons is 32. The mass number for the first case is 32 + 30 = 62, and the isotope name is germanium - 62. For the second case with 32 protons and 32 neutrons, the mass number is 32+32 = 64, and the isotope name is germanium - 64.

Answer:

Isotope Name	# of Protons	# of Neutrons	# of Electrons
Germanium - 62	32	30	32
Germanium - 64	32	32	32
