Question

How many protons are in the atom  ?

Quizplus · Accepted Answer

The atomic number of an element represents the number of protons in the nucleus of an atom. In this case, the atom's name includes "TB" which stands for "terbium" on the periodic table. Terbium has an atomic number of 65, meaning it has 65 protons. However, the given atom's name also includes "11" which likely indicates the mass number or total number of protons and neutrons in the atom's nucleus. Subtracting the atomic number of terbium (65) from the mass number (11) would result in a negative number, which is impossible. Therefore, we must assume that the "11" in the atom's name is a mistake or has some other meaning. Thus, the best answer is B, 6 protons, as this matches the atomic number of carbon (C), which has a similar mass to terbium.
