Key concepts
3 concepts
- 1
When one atom completely takes electrons from another, it forms an ionic bond, but when atoms share electrons, they form a covalent bond.
- 2
In an ionic bond, like in table salt, one atom gives up one or more electrons to another, creating oppositely charged ions that attract each other.
- 3
Only the outermost electrons, also known as valence electrons, participate in bonding, and their arrangement determines how many bonds an atom can form.

Practice
8 questions
Why are valence electrons particularly important for chemical bonding, as described in the video?
Describe the fundamental difference in how electrons behave during the formation of an ionic bond versus a covalent bond.
