Bonding makes ions
From transfer of electrons
Ions are _ particles
Charged
Ions are formed when
Atom looses or gains electrons
Why does atom loose of gain electrons
To get full outer shell - stable
Why are ions charged
Difference in numbers of protons and electrons
What are molecular ions
Particle with more than 1 atom with a charge
Negative ions _ electrons
Gain
Positive ions _ electrons
Loose
Simple ions have _ outer shells
Full
Other name for negative ions
Anions
Other name for positive ions
Cations
What is ionic bonding between
Metal + non metal
Do electrons go metal to non metal or non mental to metal
Metal to non metal
They have a strong _ force
Electrostatic
Require lots of energy to break because
Opposite charges are strong
Metal is _
Positive
Non metal is _
Negative
What is covalent bonding between
2 non metals
Ionic bonding is the _ of electrons
Transfer
In covalent bonding, electrons are _ in a pair
Shared
Weak _ force
Intermolecular
Covalent bonds have _ covalent bonds
Strong
What is the structure of ions are ionic bonding
Regular
Ionic bonds have a high/low boiling point
High
Why do ionic bonds have high boiling point
Lots of energy to break as of strong electrostatic force holding bond
Can ionic bonds conduct electricty
Only when molten or in solution so electricity can move through atoms unlike in sold as atoms are fixed unlike freely moving
Covalent bonds have high/low boiling points
Low
Why do covalent bonds have a low boiling point
Weak intermolecular force
What is metallic bonding between
2 metals
How are metallic bonds attracted
Positive ions in regular lattice and delocalised electrons
Metallic bonds have strong
Electrostatic force
Metallic bonds have a
Sea of delocalised electrons
Metallic bonds have high/low boiling point
High
Why do metallic bonds have a high melting point
Strong electrostatic force
Do metallic bonds conduct electricity
Yes
Why do metallic bonds conduct electricity
Sea of delocalised electrons
Do metallic bonds conduct heat and why
Yes - close together
Are metallic bonds malleable
Yes
Are metallic bonds ducile (molded into wires)
Yes
What is needed for a bond to have a high melting and boiling point (2)
Strong attraction force, lots of energy to overcome force
What is needed for a bond to conduct electricity
Free electrons, charged particles
