Question

espen draws an atomic model for the element neon (ne) using information from the periodic table. how many protons and electrons does he include in his 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 concept

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

Step2: Use the charge - neutrality principle

In a neutral atom, the number of electrons is equal to the number of protons. Since neon is a neutral atom, the number of electrons is also equal to the number of protons.

Answer:

B. ten protons and ten electrons
