Question

fill in the information for the cation $^{59}_{x}ni^{+3}
x$ 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

Nickel (Ni) has an atomic number of 28 from the periodic table.

Step2: Determine number of protons

The atomic number is equal to the number of protons. So, number of protons = 28.

Step3: Calculate number of neutrons

Mass - number = 59, atomic - number = 28. Number of neutrons = mass - number - atomic - number = 59 - 28=31.

Step4: Find number of electrons

For a neutral atom, number of electrons = number of protons. But this is a + 3 cation. So number of electrons = number of protons - 3 = 28 - 3 = 25.

Step5: Define number of nucleons

Nucleons are protons + neutrons. So number of nucleons = 59 (which is the mass - number).

Answer:

1. B. 28
2. B. 28
3. E. 31
4. D. 25
5. A. 59
