Simple Molecules and Covalent Bonding Flashcards
What is an atom
The stablest part of an element
What are atoms made up of
Protons
Neutrons
Electrons
Is the mass number at the top or bottom of an element
Top
What does the mass number include
The total amount of protons and neutrons
What is the test of water
Add anhydrous copper sulphate and if it is water then it will turn blue
What is covalent bonding
the bond between the positive nuclei and the shared pair of electrons
Are just non-metals covalent or ionic bonding
Covalent
What is stronger, covalent bonding or ionic bonding.
Ionic compounds form giant latices. These have high melting points and boiling points. as lots of energy is needed to separate the ions.
Do the covalent bonds break when holding the atoms together.
NO
The higher the boiling point the……intermolecular forces there are
Stronger
