Ionic Compounds - Study Guide for Content Mastery

The force that holds two atoms together is called a(n) _________________.

• chemical bond

• ionic bond

• covalent bond

• metallic bond

Such an attachment may form by the attraction of the positively charged (2) ________________ of one atom for the negatively charged (3) ________________ of another atom, or by the attraction of charged atoms, which are called (4) _________________.

• (2) ions, (3) electrons, (4) ions

• (2) protons, (3) neutrons, (4) molecules

• (2) neutrons, (3) protons, (4) atoms

• (2) electrons, (3) ions, (4) protons

The attractions may also involve (5) ________________ electrons, which are the electrons in the outermost (6) ________________.

• (5) valence (6) shell

• (5) core (6) nucleus

• (5) bonding (6) layer

• (5) free (6) orbit

The (7) ________________ are a family of elements that have very little tendency to react. Most of these elements have a set of eight outermost electrons, which is called a stable (8) ________________.

• noble gases, eight

• alkali metals, five

• halogens, seven

• transition metals, eight

The relatively stable electron structures developed by loss of electrons in certain elements of groups 1B, 2B, 3A, and 4A are called (9) ________________.

• noble gas configurations

• ionic bonds

• covalent bonds

• metallic bonds

A positively charged ion is called an anion. True or False.

• True

• False

Elements in group 1A lose their one valence electron, forming an ion with a 1+ charge.

• True

• False

Elements tend to react so that they acquire the electron structure of a halogen.

• True

• False

A sodium atom tends to lose one electron when it reacts.

• True

• False

The electron structure of a zinc ion (Zn2+) is an example of a pseudo-noble gas formation.

• True

• False
