the relative mass of particles protons, neutrons, and electrons
Charge of the subatomic particles
What type of particle is charged
ions
The top number of a Nuclear symbol
Relative Atomic mass
Distillation
simple distillation- good for separating a liquid from a solution if they have very different boiling points
fractional distillation- used to seperated mixtures with or without similar boiling points
Properties of metals
Non metal properties
Trends of group 1
Reaction with Oxygen produces a metal oxide
Reaction with Chlorine produces salt
Reaction with water produces hydrogen gas (violent reaction) metal hydroxide
As you go down:
Trends of group 7 (halogens)
Covalent bonding
As you go down:
become LESS REACTIVE- it’s harder to gain an extra electron, because the outer shell’s further from the nucleus
Higher melting and boiling points
higher atomic masses
Ions are called halides
Displacement reactions
Diatomic
Trends of group 0 (noble gases)
Full outer shell makes them non reactive
