(a)
Interpretation Introduction
Interpretation: The smaller parts to which atoms can be broken need to be determined.
Concept Introduction: The atomic model defines atom as a smallest part but according to the modern atomic theory, atoms can be divided. The subatomic particles are protons, electrons and neutrons.
(b)
Interpretation Introduction
Interpretation: The difference and similarity between the atoms of hydrogen element needs to be explained.
Concept Introduction: According to atomic theory, atoms of same elements have similar properties. The modern atomic theory, introduced the concept of isotopes. The isotope is defined as atoms of same element with different number of neutrons. For them, atomic number is same but mass number is different.
(c)
Interpretation Introduction
Interpretation: The difference and similarity between the atom of hydrogen and helium needs to be determined.
Concept Introduction: According to atomic theory, two atoms of different elements have different properties.
(d)
Interpretation Introduction
Interpretation: The difference between hydrogen peroxide and water needs to be explained.
Concept Introduction: According to law of multiple proportions, two elements can combine in different ratios to form different compounds.
(e)
Interpretation Introduction
Interpretation: The reason for mass to be conserved in a chemical reaction needs to be explained.
Concept Introduction: According to law of conservation of mass, it can neither be created nor destroyed in any chemical reaction.
