anion
If an atom donates or accepts an electron it is considered an ion.
No, nonmetals do not always have higher electron affinity than metals. Electron affinity depends on the specific element and its position in the periodic table. Some metals can have higher electron affinities than certain nonmetals.
A Lewis acid accepts an electron pair.
A substance that accepts an electron pair is known as a Lewis acid. Lewis acids are typically electron-deficient species that can form coordinate covalent bonds with electron-rich species, or Lewis bases, which donate an electron pair. Examples of Lewis acids include metal cations, certain nonmetals like boron trifluoride (BF3), and transition metal complexes. This interaction is fundamental in many chemical reactions, including catalysis and coordination chemistry.
Metals have a greater tendency to lose electrons and form positive ions compared to nonmetals. This is because metals typically have fewer outer electrons which makes it easier for them to lose those electrons and achieve a stable electron configuration.
An ion
Negative.
They tend to fiil the outermost electron shell.
Nonmetals tend to gain electrons to become negatively charged ions, increasing in size due to the addition of the electron(s). This is because the added electron(s) repel the existing electrons, causing the electron cloud to expand and the ion to be larger than the neutral atom.
If an atom donates or accepts an electron it is considered an ion.
Nonmetals tend to gain electrons to achieve a stable electron configuration and become more like noble gases. This results in a negative oxidation number because they gain electrons rather than lose them.
Bromine tends to gain one electron to achieve a stable electron configuration, making it an electron acceptor (accepts one electron).
No, nonmetals do not always have higher electron affinity than metals. Electron affinity depends on the specific element and its position in the periodic table. Some metals can have higher electron affinities than certain nonmetals.
After chlorine accepts the electron from sodium, it becomes a chloride ion with a negative charge of -1.

Oxygen accepts the electrons at the end of the electron transport chain, ultimately forming water.
