(a)
Interpretation:
The simple binary ionic compound formed when the pair of element reacts with each other is to be stated.
Concept Introduction:
The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electron configuration. The description of every electron that is moving freely in an orbital is given by the electron configuration of that atom.
Atoms lose or gain electrons to become stable by attaining nearest noble gas configuration. While doing so, they are converted to their respective ions. The positive ion and the negative ion combine to form their corresponding salt.

- 7.30 The bond in HF is said to be polar, with the hydrogen carrying a partial positive charge. For this to be true, the hydrogen atom must have less than one electron around it. Yet the Lewis dot structure of HF attributes two electrons to hydrogen. Draw a picture of the electron density distribution for HF and use it to describe how the hydrogen atom can carry a partial positive charge. How can these two models of the HF bond (the electron density and the Lewis structure) seem so different and yet describe the same thing?arrow_forward7.50 Chemical species are said to be isoelectronic if they have the same Lewis structure (regardless of charge).

- What information can you use to predict whether a bond between two atoms is covalent or ionic?arrow_forwardCH3COCH3 (acetone) is a common laboratory solvent that is often used in nail polish remover. Its Lewis structure and space-filling molecular image are shown here: Acetone is a polar molecule; the oxygen end has a slightly negative charge (oxygen is more electronegative), whereas the carbon and hydrogen end has a slightly positive charge. In liquid acetone, the molecules are attracted to each other via these polar ends-the positive end of one molecule is attracted to the negative end of its neighbor-and therefore align as shown here: Draw a Lewis structure and space-filling molecular image for CH2Cl2 (dichloromethane), another common laboratory solvent.
