Covalent Bonds

Cards (12)

Are covalent compounds brittle or malleable, when they are a solid? 
brittle
What is a Lewis (electron dot) structure?
It shows the electron dot diagram of the atoms and the electrons that are being shared between atoms
What is a structural formula? 
It represents the covalent bonds as dashes
Do covalent compounds conduct electricity?
No, because they don't have electrons or ions moving freely
What kind of melting point do covalent compounds have?
low because the molecules can move freely
Which is a harder substance, ionic or covalent?
ionic because they form multiple bonds
Which kind of bond is the strongest?
covalent
How do covalent bonds satisfy the octet rule?
they gain electrons by sharing them
diatomic elements
2 atoms of the same element covalently bonded
Which type of elements form covalent bonds?
nonmetals
attraction in covalent bonds
shared electrons are attracted to each nucleus
Covalent bond 
the sharing of a pair of valence electrons by two atoms
