Covalent Bondibg Flashcards
What is covalent bonding
Non-metal atoms can share electrons with other non-metal atoms to obtain a full outer shell of electrons
How to atoms form covalent bonds
Sharing pairs of electrons
What do two or more atoms covalent lay bonded together make
Molecules
What are shared electrons called
bonding electrons and occur in pairs
What are electrons not involved in covalent bonds called
Non bonding electrons
Why do simple covalent molecules not conduct electricity
Do not contain free electrons
What is a difference between covalent bond and ionic bonds?
Covalent bonds share electrons between two atoms, they are not transferred and no ions are formed.
What are simple molecules
Covalent substances tend to have small molecular structures, such as Cl2, H2O or CO2
Covalent molecules can be big like
Polymers and giant covalent structures
What are common polymers
Polythene and polyvinyl chloride (PVC)
What covalent bonded substances have giant covalent structures?
graphite, diamond, and silicon dioxide
