lose electrons
An atom with 3 electrons in level M would tend to either gain 5 electrons to complete level M or lose 3 electrons to complete the previous level. The tendency would depend on the element and its electronegativity.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
A nitrogen atom needs to gain 3 electrons in order to attain a noble-gas electron configuration, similar to that of neon. This would allow the nitrogen atom to fill its outermost energy level and achieve greater stability.
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose electrons.
A sulfur atom needs to gain two electrons or share electrons with other atoms to have a full valence level. Sulfur has six valence electrons and can achieve stability by forming two additional bonds.
It would gain 2 electrons.
An atom with 3 electrons in level M would tend to either gain 5 electrons to complete level M or lose 3 electrons to complete the previous level. The tendency would depend on the element and its electronegativity.
Four.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.

Lithium loses electrons.
An electronegative atom gain electrons.
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose electrons.
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
they need to either gain or lose electrons to create an octet. It depends on the atom. an octet is when an atom has a full outermost energy level
A sulfur atom needs to gain two electrons or share electrons with other atoms to have a full valence level. Sulfur has six valence electrons and can achieve stability by forming two additional bonds.
The number of electrons is specific for each element.
