Question

question 10 americium has protons neutrons electrons

Explanation:

Step1: Recall atomic number property

The atomic number (top - left number) is equal to the number of protons. For americium (Am), the atomic number is 95, so the number of protons is 95.

Step2: Calculate number of neutrons

The mass number (bottom - right number, approximated to a whole number for simplicity in this context) is approximately 243. The number of neutrons is calculated as mass number - atomic number. So, \(243 - 95=148\).

Step3: Recall electron - proton relationship

In a neutral atom, the number of electrons is equal to the number of protons. So the number of electrons is 95.

Answer:

Protons: 95
Neutrons: 148
Electrons: 95
