The number of protons in a neutral atom is balanced by an equal number of
A)electron shells that surround the nucleus.
B)neutrons in the nucleus.
C)orbital electrons.
D)none of the above

Question

Quizplus · Accepted Answer

The number of protons in an atom determines its atomic number and its identity as an element. In a neutral atom, the number of protons and electrons is equal, balancing the overall charge. Therefore, the number of protons is balanced by an equal number of orbital electrons. Neutrons are found in the nucleus but they do not balance the number of protons in a neutral atom. Electron shells surround the nucleus, but the number of shells is determined by the number of electrons, not the number of protons.
