Concept explainers
(a)
Interpretation:
The Lewis structure of the given polyatomic ion is to be drawn.
Concept introduction:
The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. These dots represent the number of electrons present in the outermost shell of an element.

The Lewis structure of the given polyatomic ion is to be drawn.
Concept introduction:
The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. These dots represent the number of electrons present in the outermost shell of an element.
(c)
Interpretation:
The Lewis structure of the given polyatomic ion is to be drawn.
Concept introduction:
The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. These dots represent the number of electrons present in the outermost shell of an element.

- What are bus? How are ions formed from atoms? Do isolated atoms form ions spontaneously? To what do the termscationandanionrefer? In terms of subatomic particles, how is an ion related to the atom from which it is formed? Does the nucleus of an atom change when the atom is converted into an ion? How can the periodic table be used to predict what ion an element’s atoms will form?arrow_forwardIdentify the polyatomic anion (including its proper charge) in each of the following ionic compounds. How many protons and electrons are present in each polyatomic anion? a. NaClO 2 b. Al(OCN) 3arrow_forwardIonic compounds do not consist of molecules, but covalent compounds generally do. Why is it incorrect to refer to a molecule of an ionic compound? As part of your answer, draw two scenes, representing atoms as circles: a. Draw at least 6 copies of NaCl showing how it is bonded. b. Draw at least 6 copies of BrCl showing how it is bonded. Then explain what is meant by a molecule and why it is correct to state that most covalent compounds exist as molecules, but ionic compounds do not exist as molecules. Take a picture of your drawing and explanation and insert it in the answer box.arrow_forward
- Naming ionic compounds For each type of ionic compound, review the names and chemical formulas of the compounds. Then devise a set of rules to name each type of ionic compound.
