The atom needs to gain an electron so it has more than the protons
Hope I helped
Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.
It has gained one or more electrons, and will be attracted to positively charged ions.
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.
Electron affinity is the energy released when an atom gains an electron to form a negative ion, while electron gain enthalpy is the enthalpy change accompanying the addition of an electron to a gaseous atom. Electron affinity is a specific term used in the context of forming an ion, while electron gain enthalpy is a general term for the enthalpy change associated with gaining an electron.
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
a negative ion... this was Ben McClanahan for you A+ people out there :))
When atoms lose or gain an electron, they become ions. If an atom loses an electron, it becomes positively charged and is called a cation. If an atom gains an electron, it becomes negatively charged and is called an anion.
Lose or gain an electron
An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with a negative charge.
Gain an electron.
The atom may gain or lose an electron either making it positive or negative.
Well an electron is negative so negative i guess But The atom is always neutral because the number of protons = electons
when atoms gain electrons they acquire negative charge
electrons... and thus one unit of negative charge....

to become stable, it will gain an electron from a metallic atom otherwise it will mutually share electron(s) with another non - metallic atom, or even with itself
