Question

use your periodic table to answer the following.
a. number of protons
b. number of electron shells
c. number of electrons
d. number of electrons in outer shell
e. element

Explanation:

Step1: Determine number of protons

The number of protons is given as \(7\) (from \(7P\) in the diagram).

Step2: Determine number of electron shells

Count the concentric circles (shells) around the nucleus. There are \(2\) shells.

Step3: Determine number of electrons

In a neutral atom, number of electrons = number of protons. So, electrons \(= 7\).

Step4: Determine electrons in outer shell

First shell holds \(2\) electrons. Total electrons \(= 7\), so outer shell has \(7 - 2=5\) electrons.

Step5: Identify the element

Element with atomic number \(7\) (number of protons) is Nitrogen (\(N\)).

Answer:

a. \(7\)
b. \(2\)
c. \(7\)
d. \(5\)
e. Nitrogen (\(N\))
