Chemical Bonds

Typically, atoms gain or lose electrons to achieve

• an exchange of energy

• vaporization

• a stable electron configuration

• ionization

Which of the following lists contain 3 elements with stable electron configurations?

• lithium, krypton, argon

• helium, xenon, neon

• argon, neon, barium

• xenon, neon, boron

Consider the electron dot diagrams for lithium, carbon, fluorine, and neon. Choose the statement that correctly identifies the most stable of the elements.

• Fluorine is the most stable element because it has to gain only one electron to achieve a stable configuration

• carbon is the most stable because it can form 4 bonds

• Lithium is the most stable element because it has to lose only one electron to achieve a stable configuration

• Neon is the most stable element because its highest occupied energy level is filled

The formation of an ionic bond involves the

• sharing of electrons between 2 nonmetals

• transfer of electrons between 2 nonmentals

• sharing of electrons between a metal and non metal

• transfer of electrons between a metal and a nonmetal

In a polar covalent bond

• a cation is bonded to an anion

• electrons are shared qually between atoms

• electrons are transferred between atoms

• electrons are not shared equally between atoms

The elements most likely to form more than one type of ion are teh

• transition metals

• halogens

• alkali metals

• alkaline earth metals

Which of the following formulas represent a compound whose molecules contain a triple bond

• O=C=O

• O₃

• SO₃

• 

Fluorine, F, forms an ionic compound with lithium, Li. What is the name of this compound

• Lithium monofluorine

• Lithium fluorine

• Lithium fluoride

• Fluorine Lithium

Alkali metals, alkaline earth metals, and aluminium all form ions with positive charges equal to their

• group number

• period

• atomic mass

• atomic number

What type of bond is being illustrated by the line drawn between the atoms shown in the picture? H-H

• unstable

• metallic
