INORGANIC CHEMISTRY 1

Question 1

GROUP (on periodic table)

Answer 1

Vertical column of elements in the periodic table. The elements have similar properties because they have the same outer electron arrangements.

Can work out how many electrons in outer shell depending on group number.

Question 2

PERIOD

Answer 2

A horizontal row of elements in the periodic table. There are trends in the properties of elements as we cross a period. (Normally gets more volatile)

Number of shells depend on period number.

Question 3

PERIODICITY

Answer 3

The regular recurrence of the properties of elements when they are arranged in atomic number order as in the periodic table.

Question 4

ALKALINE EARTH METALS

Answer 4

The metals in Group 2

Question 5

DISPLACEMENT REACTION

Answer 5

A chemical reaction in which one atom or group of atoms replace another in the compound.

Normally more reactive metal replaces less reactive metal in salt.

Question 6

DISPROPORTIONATION

Answer 6

Describes a redox reaction in which the oxidation number of some atoms of a particular element increases and that of other atoms of the same element decreases.

So same element get oxidised and reduced.
