#1
Front (Question)

covalent bond meaning

Back (Answer)

-occurs between two atoms that share a pair/more pairs of electrons

#2
Front (Question)

Why does covalent bonds happen?

Back (Answer)

• as nonmetals can only gain electrons - to complete their outer shell thy must share a pair of electrons

#3
Front (Question)

Giant covalent structures

Back (Answer)

• consists of small molecules/atoms - held together by a network of covalent bonds

#4
Front (Question)

Inter molecular forces

Back (Answer)

• forces of attraction • between covalently bonded molecules in simple molecular substances • weak forces • not a lot of energy is needed to break them • forces increase with the size of the molecule

#5
Front (Question)

Large molecules have ..

Back (Answer)

higher melting/boiling points

#6
Front (Question)

polymers

Back (Answer)

• made up from many small reactive molecules • bonded to each other • form long chains

#7
Front (Question)

why can’t compounds from simple molecules not be conductors

Back (Answer)

• they have no overall charge - so they can’t carry electrical charge

#8
Front (Question)

simple molecule

Back (Answer)

contains a few atoms that are held together by covalent bonds
