Answer:
3,6,6...................................
Answer: The correct answer is the option: B. An element with eight valence electrons is chemically unstable.
Explanation:
Hello! Let's solve this!
We will analyze each of the options:
A. The group number of the element provides a clue to the number of valence electrons: it is correct, since it provides the number of valence electrons.
B. An element with eight valence electrons is chemically unstable: this is not correct, since elements with eight electrons in the valence shell cannot react because they already have the last complete shell. Therefore, they are chemically stable.
C. The points must be placed one at a time on each side of the chemical symbol: it is correct, because that is the way to make the point diagram.
D. An atom is chemically stable if all the points are paired: this is correct since this verifies that the point diagram has been done well.
We conclude that the correct answer is the option: B. An element with eight valence electrons is chemically unstable.
Hope this helps..... Stay safe and have a Merry Christmas!!!!!!!!! :D
I'd say the correct answer is: Noodles rising and falling apart in boiling water.
electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy.
<span>The skull, vertebral column, and thoracic cage are the main part of the axial skeleton.
So, the answer is that the skull, vertebral column, and thoraic cage form the axial skeleton.
If you look at a diagram of the axial skeleton you will see the bones of the head (skull) , the spine (vertebral column), and the rib cage (toracic cage)
