Question

isotopes
lt: i can determine mass number from number of neutrons and vice versa.
isotope atoms of the same element, each with a different number of neutrons
isotopic notation shows the mass number, and atomic number on the element symbol
mass number the sum of the number of protons and neutrons, always a whole number
atomic number the number of protons in an atom all atoms of the same element have the same atomic number
isotopes show what you know
using a periodic table, fill in the data table.

Explanation:

Step1: Recall atomic - related concepts

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 mass number is the sum of protons and neutrons, so the number of neutrons = mass number - atomic number.

Step2: Fill the first row (for \(^{22}_{10}Ne\))

It is already filled correctly as per the rules. Atomic number = 10, so protons = 10 and electrons = 10. Mass number = 22, number of neutrons=mass number - atomic number = 22 - 10=12.

Step3: Fill the second row

Atomic number = 20, so protons = 20 and electrons = 20. Mass number = 42, number of neutrons = 42 - 20 = 22. Isotopic notation: \(^{42}_{20}Ca\) (assuming it's calcium as atomic number 20).

Step4: Fill the third row

Number of neutrons = 38, mass number = 86. Atomic number=mass number - number of neutrons = 86 - 38 = 48, so protons = 48 and electrons = 48. Isotopic notation: \(^{86}_{48}Cd\) (assuming it's cadmium as atomic number 48).

Step5: Fill the fourth row (for \(^{65}_{29}Cu\))

Atomic number = 29, so protons = 29 and electrons = 29. Mass number = 65, number of neutrons = 65 - 29 = 36.

Step6: Fill the fifth row

Electrons = 15, so protons = 15 (neutral atom), atomic number = 15 (phosphorus). Mass number=number of neutrons + atomic number = 14+15 = 29. Isotopic notation: \(^{29}_{15}P\)

Answer:

Isotopic Notation	Mass Number	Atomic Number	Protons	Neutrons	Electrons
\(^{42}_{20}Ca\)	42	20	20	22	20
\(^{86}_{48}Cd\)	86	48	48	38	48
\(^{65}_{29}Cu\)	65	29	29	36	29
\(^{29}_{15}P\)	29	15	15	14	15
