Question

an atom of iron contains how may electrons?
a. 22
b. 8
c. 4
d. 26

Explanation:

Identify the element and its atomic number

We need to find the number of electrons in a neutral atom of iron. Iron is a chemical element represented by the symbol \(Fe\).

Determine the number of electrons

In a neutral atom, the number of electrons is equal to the number of protons, which is defined by the element's atomic number. Iron has an atomic number of 26. Therefore, a neutral atom of iron contains 26 protons and 26 electrons.
