Concept explainers
(a)
Interpretation:
The charges for the monoatomic ions of the element Magnesium has to be written.
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 charges for the monoatomic ions of the element Phosphorous has to be written.
Concept Introduction:
“Refer sub-part (a)”.
(c)
Interpretation:
The charges for the monoatomic ions of the element Iron has to be written.
Concept Introduction:
“Refer sub-part (a)”.
(d)
Interpretation:
The charges for the monoatomic ions of the element Selenium has to be written.
Concept Introduction:
“Refer sub-part (a)”.
