Question

How many protons, neutrons, and electrons does an atom of neon contain based on the atomic symbol?

A) Protons: 10, Neutrons: 10, Electrons: 10
B) Protons: 10, Neutrons: 18, Electrons: 10
C) Protons: 20, Neutrons: 10, Electrons: 20
D) Protons: 10, Neutrons: 10, Electrons: 20

Answer 1

An atom of neon, based on the atomic symbol, contains 10 protons, 10 neutrons, and 10 electrons.

Step-by-step explanation:

The atomic symbol for neon is Ne. Based on the atomic symbol, an atom of neon contains:

• Protons: 10
• Neutrons: 10
• Electrons: 10

The atomic number of neon is 10, which represents the number of protons and electrons in the atom. The atomic mass of neon is not needed to determine the number of protons, neutrons, and electrons, as it is the weighted average of all the naturally occurring isotopes of neon.
