Question

Identify the number of core and valence electrons for each atom.

A) 2 core, 4 valence
B) 8 core, 2 valence
C) 10 core, 6 valence
D) 18 core, 8 valence

Answer 1

The number of core and valence electrons for each atom is different for each option.

Step-by-step explanation:

For each atom:

1. A) 2 core, 4 valence
2. B) 8 core, 2 valence
3. C) 10 core, 6 valence
4. D) 18 core, 8 valence

• A) Each atom has a total of 6 valence electrons, with 2 core electrons.
• B) Each atom has a total of 8 valence electrons, with 8 core electrons.
• C) Each atom has a total of 16 valence electrons, with 10 core electrons.
• D) Each atom has a total of 16 valence electrons, with 18 core electrons.
