A Lewis acid.
A Lewis acid accepts an electron pair.
oxide
If an atom donates or accepts an electron it is considered an ion.
There are three definitions for acids and bases. Arrhenius definition: An acid is a substance that produces hydrogen (H+) ions in water while a base produces hydroxide (OH-) ions. Bronsted-Lowry definition: An acid gives up or donates a proton (H+) to another molecule while a base accepts a proton. Lewis definition: An acid accepts an electron pair in bonding to another molecule/ion while a base donates and electron pair. Note that if a substance meets one of the first two definitions it probably meets the others as well.
No, by the Lewis definition they accept an electron pair.
The correct answer is acid.
A Lewis acid accepts an electron pair.
The correct answer is acid.
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
The correct answer is acid.
oxide
The correct answer is acid.
A Lewis acid accepts an electron pair from a base. ---APEX--
An acid accepts an electron pair from a base.
An oxidizer is a substance that oxidizes another substance. It does this by creating a reaction that accepts an electron from another place or species.
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
As the definition of a Lewis acid says:"Capable of accepting electron pair (from a (Lewis) base".So H+ and Ag+ are both Lewis acids compared in the following reaction with ammonia:(in which the N-atom is donating the unbound electron pair as being a 'Lewis' base)H+ + NH3 --> HNH3+Ag+ + 2NH3 --> Ag(NH3)2+[As you can see the 'Lewis' definition is much wider than the 'Bronsted/Lowry': it needs free places for an electron pair, not H+]
