why atoms tend to gain ar lase electeon?
Answers
Explanation:
Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms).
Answer:
Stability.
If atom results in full valance shell, it achieves noble gas configuration and is unlikely to react.
If atoms are unlikely to react, low in energy = comfortable/stable, they remain that way. Atoms or anything with high energy will use it do work and change (gain or lose electron)
Metals on left of periodic table, give electrons and arrive at full valence shell (noble gas configuration) and become very stable.
Nonmetals on right of periodic table, take electrons and arrive at full valence shell (noble gas configuration) and become very stable.
Whether a reaction happens or not depends on THERMODYNAMICS, specifically reactants with high energy are unsettled and naturally do something to arrive at more stable state or low energy. This is SPONTANEOUS.
to move from low energy to high energy requires an input of energy. So IT IS POSSIBLE for the reverse to happen, that metals gain electrons and nonmetals lose electrons, but this is VERY unstable, so if it ever happens, it will likely be undone.
Atoms lose or gain electrons to reach a more stable, more comfortable, lower energy state.
