1.3 Bonding Flashcards
1
Q
Define ionic bonding.
A
Ionic bonding is the electrostatic force of attraction between oppositely charged ions formed by electron transfer.
2
Q
Metal atoms lose electrons to form…
A
positive ions
3
Q
Non-metal atoms gain electrons to from…
A
negative ions
4
Q
How are ionic crystals structured?
A
Giant lattice of ions
5
Q
Why are positive ions smalled compared to their atoms?
A
It has one less shell of electrons and the ratio of protons to electrons has increased so there is greater net force on remaining electrons holding them more closely.
6
Q
Why does ionic radii increase going down a group?
A
This is because as one goes down the group the ions have more shells of electrons.
7
Q
What is a covalent bond?
A
A covalent bond is a shared pair of electrons.
