Structure and bonding

Question	Answer
What three things make up an atom? State the charges ans mass.	Protons (+1, mass=1) Electrons (-1, no mass) Neutrons (0, mass+1)
What is the atomic number equal to?	Number of Protons (same as the number of neutrons)
How can you find out the number of neutrons?	mass - atomic number
What are isotopes?	Elements with the same number of protons, but the neutron number is different.
In ionic bonding, what type of ions bond together? Is this between non metals or metals?	Positive and negative Non metals and metals
In ionic bonding what is every ion surrounded by?	Oppositely charged ions.
In ionic bonding, how are all the ions held together?	By an electrostatic attraction.
In ionic bonding, what is the structure like? What are they likely to form because of this?	A giant lattice, so Ionic compounds often form crystals as a result.
Ionic compounds are very strongly bonded this makes them have....	A high melting/boiling point.
