Atoms whose outer shell is filled have eight valence electrons and belong to Group XVIII. This group is known as the noble gases.

When a compound is formed by 2 or more atoms of different elements the outer electron shell of the compound is completely filled with electrons?

This answer is True!


Are atoms most stable when they have partially filled shells?

No, atoms are most stable when their outermost electron shells are completely filled. This is because a full outer shell results in a lower energy state, making the atom more stable. Partially filled shells can lead to greater reactivity as atoms seek to fill or empty their outermost shell.

When a compound is joined by two or more atoms of different element joining the outer electron the compound is filled with electrons?

When a compound is formed from two or more atoms of different elements, the chemical bonds that form cause the atoms in the compound to have filled valence shells.


Why does chlorine have a negative ion?

Chlorine becomes a negative ion by gaining one electron to achieve a full outer electron shell, following the octet rule which states that atoms are most stable when their outer electron shell is filled with 8 electrons.


What is a partially filled outer electron level makes with?

A completley filled out electron level makes the atom stable


Why does a atom with a filled outer energy level of electrons not react well?

Because it's in a stable state. Atoms with an electron 'missing' from their outer shell will always try to 'grab' one back to stabilize themselves. This is often done by combining with other atoms and 'sharing' an electron in order to reach stability.


Are the outer electron shells always filled first?

No. The inner shells are filled first.
