* Protons: The number of protons defines the element. Americium (Am) has 95 protons.
* Electrons: In a neutral atom, the number of electrons equals the number of protons. So, a neutral americium atom also has 95 electrons.
* Neutrons: This is where it gets complicated. Americium has several isotopes, each with a different number of neutrons. The most common isotope is Americium-241, which has 146 neutrons.
Here's a summary:
* Americium-241:
* Protons: 95
* Neutrons: 146
* Electrons: 95
To find the number of neutrons for other americium isotopes, you need to subtract the atomic number (95) from the mass number of the isotope.
