What else can I help you with?
An atom is chemically stable when it’s outer ____ is completely filled with?
Its outer shell is filled with electrons.
What is an atom that will lose or gain electrons until they have a full outer shell?
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
When an atom forms an ion describe the outer shell of the ion?
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
When an atom's outer layer is filled with electron it is?
Atoms whose outer shell is filled have eight valence electrons and belong to Group XVIII. This group is known as the noble gases.
What happens when an atom loses an electron in its outer most shell?
it becomes a positive ion
What happens when a chlorine atom an electron in its outer energy shell?
It becomes a negative ion.
What is an atom when it has 8 electrons in the outer shell?
An atom with 8 electrons in its outer shell is stable and is considered to have a full valence shell. This configuration is known as the octet rule, which means the atom is unlikely to form chemical bonds with other atoms as it is already in a stable state.
What happens when a sodium atom loses an electron in its outer shell?
When a sodium atom loses an electron in its outer shell, it forms a positively charged sodium ion (Na+). This process happens in order to achieve a stable electron configuration similar to that of a noble gas, which typically have a full outer shell of electrons.
When happens when a chlorine atom gains an electrons in its outer energy shell?
It becomes a negative ion.
What happens when a chlorine atom gains an electron its outer energy shell?
It becomes a negative ion.
What happens when a chlorine atom gains an electronic In its outer energy shell?
It becomes a negative ion.
What is the name given to the outer shell of the atom?
The outer shell of an atom is the valence shell, which contains the valence electrons.
