Question

fill in the information for the isotope ni - 60, or $^{60}_{x}ni$. x is the atomic number from the periodic table, 1. 2 number of protons. 3 number of neutrons. 4 number of electrons. 5 number of nucleons. a. 59 b. 28 c. 32 d. 25 e. 31 f. 60

Explanation:

Step1: Find atomic number of Ni

Nickel (Ni) has an atomic number of 28 from the periodic table. So, X = 28.

Step2: Determine number of protons

The atomic number is equal to the number of protons. For Ni - 60, number of protons = 28.

Step3: Calculate number of neutrons

The mass - number is 60. Number of neutrons = Mass number - Atomic number. So, number of neutrons = 60 - 28=32.

Step4: Find number of electrons

In a neutral atom, number of electrons = number of protons. So, number of electrons = 28.

Step5: Define number of nucleons

Nucleons are protons and neutrons. Number of nucleons = Mass number = 60.

Answer:

1. B. 28
2. B. 28
3. C. 32
4. B. 28
5. F. 60
