Question

*How many neutrons make up one of these potassium atoms?*
19
20
38
58

Answer 1

The number of neutrons in a potassium atom cannot be determined without knowing the mass number.

Step-by-step explanation:

Potassium (K) has an atomic number of 19, which means it has 19 protons in its nucleus. The atomic number gives the number of protons in an atom.

To find the number of neutrons, we subtract the atomic number from the mass number. In this case, the mass number of the given potassium atom is not provided, so we cannot determine the number of neutrons for this specific atom.
