Question

which statement best explains the octet rule?
A) atoms gain , lose, or share electrons at achieve a full valence shell
B) compounds always consist of 8 shell
C) molecules always of 8 atoms
D) all atoms require of 8 electrons to from bonds

Answer 1

A, atoms gain, lose, or share electrons to achieve a full valence shell.

Answer 2

An  octet rule occurs when atoms gain , lose, or share electrons to achieve a full valence shell of 8 electrons.

• To attain stability, atoms of element must gain, loose or share electrons to obtain the octet configuration, This means that their outermost shell must have 8 electrons.

• elements that give out electrons to achieve the octet rule are called metals.
• Elements that gain electrons to achieve the octet rule are called non metals.
• When there is sharing of electrons by elements to attain stability, Covalent compounds are  formed
