How many protons (p),neutrons (n),and electrons (e)are in one atom of 
?

Quizplus · Accepted Answer

The atomic number of the element (11) tells us there are 11 protons in the nucleus. The given symbol (TB4939_11) indicates the atomic mass is 23, which means there are 23 - 11 = 12 neutrons. In a neutral atom, the number of electrons is equal to the number of protons, so there are also 11 electrons. Choice B matches these numbers.
