4.2.1 Bonding, structure, and the properties of matter Flashcards
1
Q
What is ionic bonding?
A
Ionic bonding is the electrostatic attraction between positive and negative ions.
It is a relatively strong attraction.
2
Q
How are ionic compounds held together?
A
● They are held together in a giant lattice.
● It’s a regular structure that extends in all directions in a substance.
● Electrostatic attraction between positive and negative ions holds
the structure together.
3
Q
How are ionic compounds formed?
A
Reaction of a metal with a non-metal.
Electron transfer occurs - metal gives away its outer shell electrons to
non-metal.
4
Q
What is a covalent bond?
A
Covalent bond is a shared pair of electrons between two atoms.
