Scelta multipla
Why do anions form?
A
Because atoms share electrons equally with other atoms
B
Because atoms split into smaller neutral particles
C
Because atoms gain electrons to achieve a stable, full valence shell
D
Because atoms lose electrons to become positively charged
Guida verificata passo dopo passo1
Understand that anions are negatively charged ions formed when atoms gain electrons.
Recall that atoms tend to achieve a stable electron configuration, often resembling the nearest noble gas with a full valence shell.
Recognize that gaining electrons increases the number of negatively charged particles (electrons) relative to positively charged protons, resulting in a negative charge.
Note that this process is different from losing electrons, which forms cations (positively charged ions).
Therefore, anions form because atoms gain electrons to complete their valence shell and achieve stability.
