an ion of iron has an 26 protons, 30 neutrons, and 23 electrons. what are its atomic number, atomic mass, and net charge?
Answer: Given the information provided, we can determine the atomic number, atomic mass, and net charge of the ion of iron:
-
Atomic Number (Z):
The atomic number of an element is equal to the number of protons in its nucleus. In this case, the ion of iron has 26 protons, so its atomic number is 26. -
Atomic Mass (A):
The atomic mass of an element is the sum of the number of protons and neutrons in its nucleus. In this case, the ion of iron has 26 protons and 30 neutrons, so its atomic mass is 26 + 30 = 56. -
Net Charge:
The net charge of an ion is determined by comparing the number of protons (positive charges) and electrons (negative charges). In this case, the ion of iron has 23 electrons and 26 protons, resulting in a net positive charge of +3. This means the ion has lost three electrons.
To summarize:
- Atomic Number (Z): 26
- Atomic Mass (A): 56
- Net Charge: +3
The ion of iron in question has an atomic number of 26, an atomic mass of 56, and a net charge of +3.
