Akali metals chemical and physical properties

• shiny, soft, consistency of clay

• react violently with water so aren’t found free in nature

Alakaline Earth Metals chemical and physical properties

• Malleable, ductile, good conductors of heat and electricity

• never found in nature because they’re highly reactive

Halogens chemical and physical properties

• They are very reactive and are therefore never found free

  in nature. They occur as diatomic

Transition metals chemical and physical properties

• good conductors of heat and electricity

• Form coloured ions

• Have varied valences

• Show catalytic activity

Metalloids chemical and physical properties

Properties of both metals and non-metals

Boron, Silicon, Germaninum, Arsenic, Antimony, Tellurium, Polonium

Atomic radius definition

The distance from the centre of the atom to the boundary within which hte electron spends 90% of its time (like the size of it basically)

Atomic radius trend

Decreases from left to right. Increases up to down (so bottom left corner is the biggest)

Ionization energy definition

The minimum energy required ti remove an electron from the ground state of an isolated gaseous ion

Ionization energy, electron affinity, electronegativity trend

Increases from left to right. Decreases from right to left.

biggest is top right corner.

Oppposite to atomic radius

Electron Affinties definition

The energy change that occurs when an electron is captured by ana tom to form a negative ion.

Electronegativity definition

The ability of an atom to attarct electrons to islef in a bond. There is an assigned value to measuere this ability (0-4.0)

Noble gases physical and chemical properties

they have full outer energy and are non reactive

used for neon signs
