BH3, BF3, AlCl3 are examples. Anions are all electron rich and cations are electron deficit. You should always see the no. of electrons before saying if the given compound, if neutral, is electron rich, precise or deficient. In first case, the molecule will have a net negative charge. In second case, the molecule will have no charge.
In fact, An example is SO2. Sulphur has a total of 10 electrons bounded to it. 4 bond pairs and a lone pair. These act as good Lewis bases. If the central atom has precisely 8 electrons, it’s said to be electron precise, H2O, NH3 all are examples. Furthermore, For example- NH3 (i) Electron Deficient Hybrides – Group 13 hydrides (Compounds with hydrogen), mainly Hydrides of Al and B are calledelectron deficient hydrides. (ii) Electron Precise Hydride –The type of hydride in which the number of electrons present is equal to the number of electron required (octet or duplet). Keeping this in consideration, Electron rich: The type of hydrides which have more number of electrons than required for bonding are called electron-rich hydrides. The excess number of electrons are mainly the lone pair of electrons on the central atom. These types of compounds are usually formed by groups 15, 16 and 17 elements. Just so, Electron precise: The type of hydrides that have the exact number of electrons to form a covalent bond are called electron precise. These types of compounds are usually formed by group 14 elements. The compounds usually have a tetrahedral shape. Example CH 4, SiH 4, etc.

What kind of electron is a hydrated electron?
In simple terms a free electron that can act as an anion in a reaction is called a solvated electron. These solvated electrons are capable of reducing metal cations. Finally, if the solvent is water the anionic electron is called hydrated electron.

Why is an electron acceptor called an electron donor semiconductor?
For both types of donor or acceptor atoms, increasing dopant density increases conductivity. An extrinsic semiconductor which has been doped with electron donor atoms is called an n-type semiconductor, because the majority of charge carriers in the crystal are negative electrons.
Why are metals called electron donors when they lose an electron?
If you remove one electron, then 6 protons are pulling 5 electrons, so losing 1 more electron will require more energy and so on. Because all metal loses its electron to complete a stable configuration and give it to other elements, but there are also some non - metals donate their electron to other elements like hydrogen, nitrogen, carbon…
What is the difference between an electron donor and an electron acceptor?
In physics of semiconductors, an electron donor is a dopant atom (impurity) that, when added to a semiconductor, can form a n-type semiconductor. An electron acceptor is a dopant atom (impurity) that, when added to a semiconductor, can form a p-type semiconductor.
Who is the electron donor in the electron transport chain?
NADH is the electron donor in this system. It initiates the electron transport chain by donating electrons to NADH dehydrogenase (blue). NADH donates two electrons to NADH dehydrogenase. At the same time, the complex also pumps two protons from the matrix space of the mitochondria into the intermembrane space.
What is an electron donor and an electron acceptor?
In physics of semiconductors, an electron donor is a dopant atom (impurity) that, when added to a semiconductor, can form a n-type semiconductor . An electron acceptor is a dopant atom (impurity) that, when added to a semiconductor, can form a p-type semiconductor.

What is the difference between electron donor and electron acceptor?
An electron donor is a dopant atom (impurity) that, when added to a semiconductor, can form a n-type semiconductor. An electron acceptor is a dopant atom (impurity) that, when added to a semiconductor, can form a p-type semiconductor.
Why is an electron donor an electron acceptor complex?
The resulting electrostatic attraction provides a stabilizing force for the molecular complex. The source molecule from which the charge is transferred is called the electron donor, and the receiving molecule is called the electron acceptor, hence the name, electron-donor-acceptor-complex.
