Octet Rule & Naming Compounds

A rule that states that atoms are most stable when they have a full shell

of electrons in the outside electron shell.

• Octet Rule

• Golden Rule

• Hund's Rule

• All of the above

According to the Octet Rule, atoms of elements react with each other

in order to attain electrons in their outermost energy level or shell.

• 2

• 4

• 6

• 8

The valence electrons of representative elements are

• In s orbitals only.

• Located in the outermost occupied major energy level.

• Located closest to the nucleus.

• Located in d orbitals

How do you find the number of valence electrons in an atom?

• Use the Atomic Number

• Use the Group Number

• Use the Mass - Atomic number

• Use the Period Number

Which of the following is not true with regards to the octet rule?

• It refers to an important chemical rule of thumb

• It refers to an important principle that the atoms which bonded

  share eight outer electrons have

• It states that the atoms like to have six electrons only in their full

  outer shells

• Two notable exceptions to the octet rule are helium and

  hydrogen

It is used to describe elements that are covalently bonded and to

distinguish the compounds from ionic compounds.

• Molecular Compounds

• Chemical Formula

• Ionic Compounds

• All of the above
