Concept explainers
(a)
Interpretation:
The chemical symbol for the monoatomic ion Nitrogen has to be written with charge.
Concept Introduction:
Ions:
When one atom comes into contact with another it is the electrons of both atoms that interact. One type of interaction is for one or more electrons to be removed from one atom, forming a positive ion. Because opposite charges attract, the positive ion attracts the negative ion. This bonds the two atoms (ions) together.
Monoatomic ion:
A monoatomic ion is a single atom that has lost or gained electrons.
(b)
Interpretation:
The chemical symbol for the monoatomic ion Sulphur has to be written with charge.
Concept Introduction:
“Refer sub-part (a)”.
(c)
Interpretation:
The chemical symbol for the corresponding monoatomic ion that is Chlorine has to be written with charge.
Concept Introduction:
“Refer sub-part (a)”.
(d)
Interpretation:
The chemical symbol for the monoatomic ion Iodine has to be written with charge.
Concept Introduction:
“Refer sub-part (a)”.
