1
New cards

the relative mass of particles protons, neutrons, and electrons

  • 1- proton
  • 1 proton
  • very small (0-virtually no mass)
2
New cards

Charge of the subatomic particles

  • Proton- +1
  • Neutron- 0
  • Electron- -1
3
New cards

What type of particle is charged

ions

4
New cards

The top number of a Nuclear symbol

Relative Atomic mass

5
New cards

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

6
New cards

Properties of metals

  • Metallic bonding
  • Strong (hard to break), but can be bent or hammered into different shapes (malleable)
  • Great conductors of heat and electricity
  • shiny
  • High boiling and melting points
7
New cards

Non metal properties

  • Different properties to metals
  • dull
  • Aren’t always solid at room temperature
  • Brittle
  • Lower density
8
New cards

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:

  • Reactivity increases outer electron is more easily lost as it is further away from the nucleus of the atom meaning the electrons attraction to the nucleus is less strong
  • Lower melting and boiling points
  • higher relative atomic mass soft grey metals
9
New cards

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

10
New cards

Trends of group 0 (noble gases)

Full outer shell makes them non reactive

  • All colourless gases at room temperature
  • Non flammable
  • Boiling points increases as you move down the table (due to greater intermolecular forces between them)
