Question

1. how many protons, neutrons, and electrons should be included in the atom model of a nitrogen atom?

a) 7 protons, 2 neutrons, and 7 electrons
b) 7 protons, 7 neutrons, and 7 electrons
c) 14 protons, 2 neutrons, and 7 electrons
d) 14 protons, 7 neutrons, and 7 electrons

Explanation:

Step1: Determine the number of protons

The atomic number of nitrogen is \(7\). The atomic number is equal to the number of protons. So, the number of protons in a nitrogen atom is \(7\).

Step2: Determine the number of electrons

In a neutral atom, the number of electrons is equal to the number of protons. Since the number of protons is \(7\), the number of electrons is also \(7\).

Step3: Determine the number of neutrons

The mass number of nitrogen is \(14\). The mass number is the sum of protons and neutrons. Using the formula \(mass\ number=protons + neutrons\), we can find the number of neutrons. Substituting the values, \(14 = 7+neutrons\), so \(neutrons=14 - 7=7\).

Answer:

B. 7 protons, 7 neutrons, and 7 electrons
