Question

espan draws an atomic model for the element neon (ne) using information from the periodic table. how many protons and electrons does he include in the model?
a seven protons and seven electrons
b. ten protons and ten electrons
c. ten protons and twenty electrons
d. twenty protons and twenty electrons

Explanation:

Step1: Recall the atomic number property

The atomic number of an element is equal to the number of protons in its nucleus. For neon (Ne), the atomic number is 10. So, the number of protons is 10.

Step2: Use the charge - neutral atom property

In a neutral atom, the number of electrons is equal to the number of protons. Since neon is a neutral atom (as it is in its standard state for an atomic model), the number of electrons is also 10.

Answer:

B. ten protons and ten electrons
