* Protons: All atoms of a specific element have the same number of protons. Americium (Am) has 95 protons. This is its atomic number and defines it as americium.
* Electrons: In a neutral atom, the number of electrons equals the number of protons. So, a neutral americium atom has 95 electrons.
* Neutrons: Here's where it gets complicated. The most common isotope of americium is americium-241 (²⁴¹Am). This means it has 241 - 95 = 146 neutrons.
However, other americium isotopes exist, like americium-243 (²⁴³Am), which has 148 neutrons.
So, to summarize:
* Protons: 95
* Electrons: 95 (in a neutral atom)
* Neutrons: Varies depending on the isotope.
* ²⁴¹Am: 146 neutrons
* ²⁴³Am: 148 neutrons
* And so on...
