Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

The elements which are metallic in nature, occupy the large lower-left portion of the table. The non-metals occupy the small upper-right portion of the table. Metalloids like along the staircase line. Elements which appear in the same group have similar behaviour.

Interpretation Introduction

Interpretation:

The coloured boxes that represent a pair of elements whose compounds exhibit the law of multiple proportions are to be determined.

Concept introduction:

Law of multiple proportions states that, if two elements can combine to form more than one compound, the masses of one element that combines with a fixed mass of the other element are in the ratio of small whole numbers.

Interpretation:

The coloured boxes that represent a pair of elements that will likely form an ionic compound with the formula MX are to be determined.

Concept introduction:

Ionic compounds are formed by the interaction of metal elements with non-metal elements. In an ionic bond formation, there is a transfer of electrons between atoms. The metal elements have a tendency to lose electrons in order to gain stability, whereas non-metals acquire stability by gaining the electrons. The ions thus formed attract each other due to strong electrostatic force between them to form ionic compounds.
