Question

capacity before moving on.

• electrons on the outer most ring are known as valence electrons. these are the electrons that participate in chemical bonding.
• each dot represents one electron.

1. identify the elements shown in the bohr models below and give the number of valence electrons in each atom:

a.
element=
valence electrons =
b.
element=
valence electrons =
c.
element=
valence electrons =

1. draw bohr models for the elements listed below and state the number of valence electrons in each.

a. nitrogen (n)
b. chlorine (cl)
c. calcium
*at the top of your screen check select the to \properties\ tab. next check (√) the box in the center next to \valence,\ this will show the valence electron count for each element appear in the bottom left of its symbol on the periodic table.

1. the transition metal family is very large, which group numbers are included as part of this family? can you see a pattern for their electron numbers?

Explanation:

Problem 22 (assuming we analyze part a first, and we'll follow the same logic for b and c)

Part a:

Step 1: Count total electrons (protons = electrons in neutral atom)

Looking at the Bohr model for part a: Inner shell (first) has 2 electrons, middle shell (second) has 4 electrons, outer shell (third? Wait, no, wait—wait, Bohr model: first shell (n=1) holds max 2, second (n=2) max 8, third (n=3) max 18, etc. Wait, in the diagram, the innermost circle (n=1) has 2 electrons (let's say the black dots? Wait, maybe the colors: let's count all electrons. Let's see: the innermost (n=1) has 2 (maybe the dark blue? Wait, the diagram: center, then first shell (n=1) with 2, second shell (n=2) with 4, third shell (n=3) with 2? Wait, no, the circles: the first (innermost) circle (n=1) has 2, second (n=2) has 4, third (n=3) has 2? Wait, total electrons: 2 + 4 + 2 = 8? No, wait, maybe I miscounted. Wait, the Bohr model:[LLM SSE On Failure]
