Concept explainers
(a)
Interpretation:
Whether the representative particle in acetone is an atom, formula unit or molecule is to be stated.
Concept introduction:
The covalent bond is formed when two non-metals are combined by sharing the valence electrons. The particle that is held together by a covalent bond is known as a molecule. This can be identified when there are two non-metals in an atom.
(b)
Interpretation:
Whether the representative particle in cobalt is an atom, formula unit or molecule is to be stated.
Concept introduction:
The atom is the basic unit of a particle that cannot be broken by any chemical means. The atom shows the property of an element. Every state is composed of a neutral or an ionized atom.
(c)
Interpretation:
Whether the representative particle in magnetite is an atom, formula unit or molecule is to be stated.
Concept introduction:
In an ionic bond, the cation is attracted to an anion. This attraction is due to the opposite charges on both the ions. The particle that is held together by an ionic bond is known as formula unit. This can be identified when the particle has a metal and a non-metal.
(d)
Interpretation:
Whether the representative particle in phosphorus is an atom, formula unit or molecule is to be stated.
Concept introduction:
The covalent bond is formed when two non-metals are combined by sharing the valence electrons. The particle that is held together by a covalent bond is known as a molecule. This can be identified when there are two non-metals in an atom.
