Which of the following compounds is formed by covalent bonding?
H20
An atom of Aluminum (Al) is in Group 3A. What ion is it most likely to form to become stable?
B) Al3+
An atom of Sulfur (S) is in Group 6A. What charge will it carry when it forms a stable ionic bond?
2-
Why do Group 4A elements, such as Carbon (C), rarely form ionic charges?
Gaining or losing 4 electrons requires too much energy, so they prefer to share.
In the Lewis dot structure of a Carbon Dioxide (
CO2
𝐶𝑂2
) molecule, how many total bonding pairs (lines representing shared electrons) surround the central carbon atom?
Two double bonds
