(a)
Interpretation:
The formula for the triatomic molecule by using circular symbols to represent atoms is to be drawn.
Concept introduction:
A molecular formula represents the number of atoms of each element present in a molecule of a compound.
The number of atoms present in molecule is determined by the subscript written below the normal line in the molecular formula.
(b)
Interpretation:
The formula for a molecule of a compound containing two atoms of one element and two atoms of a second element by using circular symbols to represent atoms is to be drawn.
Concept introduction:
A molecular formula represents the number of atoms of each element present in a molecule of a compound.
The number of atoms present in molecule is determined by the subscript written below the normal line in the molecular formula.
(c)
Interpretation:
The formula for a molecule of a compound containing two atoms of one element, one atom of a second element, and four atoms of a third element by using circular symbols to represent atoms is to be drawn.
Concept introduction:
A molecular formula represents the number of atoms of each element present in a molecule of a compound.
The number of atoms present in molecule is determined by the subscript written below the normal line in the molecular formula.
(d)
Interpretation:
The formula for a molecule of a compound containing two atoms of one element, six atom of a second element, and one atom of a third element by using circular symbols to represent atoms is to be drawn.
