The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.
During the formation of a chemical bond atoms tend to complete their outer most shell or tend to reach the nearest noble gas electronic configuration by gaining on electron, by losing off electron or by sharing of electrons.
to attain the electron configuration of noble gas atoms.
I believe it's 8 valence electrons. Not quite sure.
a stable electron configuration
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
Either by losing or gaining electrons (and forming ionic compounds) or by sharing of electrons (and forming covalent compounds).
It is true. The chemical properties of atoms are primarily based on the electron configuration, particularly the number of electrons in the outer or valence shell, while the nuclear properties of atoms are primarily based on the proton/neutron configuration in the nucleus.

Because of same chemical configuration. Both are similar to each other.
By forming chemical bonds, atoms get more stable than their individual state. It can be explained by the release of energy while forming a chemical bond.

Since chemical energy is a type of potential energy, it is hard - and doubtful - to pinpoint the energy exactly. There is energy in the fact that atoms are in a certain configuration, or in the fact that atoms are separate - atoms that would be in a lower energy state if they combined. The potential energy is in the system configuration - not in any particular component.Since chemical energy is a type of potential energy, it is hard - and doubtful - to pinpoint the energy exactly.

It is called the octet rule.
the electron configuration of a noble gas
It is true. The chemical properties of atoms are primarily based on the electron configuration, particularly the number of electrons in the outer or valence shell, while the nuclear properties of atoms are primarily based on the proton/neutron configuration in the nucleus.
Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
Atoms 'join' together by forming chemical bonds in order to obtain better stability than the existence of individual atoms.
