Electrons are not
fixed
to one atom
View source
Why do metals conduct electricity and heat well?
Due to free-moving
delocalized electrons
View source

View source
How are anion names different from their normal names?
They change to reflect
ionic
form
View source
What is the bonding type between non-metals?
Covalent bonding
View source
How do non-metals bond to form molecules?
By sharing
electrons
View source
What is the structural formula for chlorine gas (Cl₂)?
Two
Cl
atoms
sharing
electrons

What does each line in a structural formula represent?
A
pair
of shared
electrons
View source
What is a double covalent bond?
Two pairs of
electrons
shared
View source
What is the number of bonds nitrogen (N₂) makes?
Three
bonds
View source
How do simple molecular structures behave?
They have low
boiling points
View source
Why can't simple molecular structures conduct electricity?
They lack free-moving
charged particles
View source
What is giant covalent bonding similar to?
The lattice nature of
ionic compounds
View source
What is diamond an example of?
A giant
covalent
structure
View source
Why is diamond hard and has a high melting point?
Due to strong
covalent bonds
