In a coordinate or dative bond, electrons required for sharing are contributed by one atom. The atom which contributes the electrons for sharing is called donor atom and the atom which shares the electrons is called acceptor atom.

Coordinate Bond Formation
Coordinate bond formation involves the sharing of electron pairs between two atoms to form a covalent bond. In this process, one atom contributes a pair of electrons while both atoms share the electrons.

Explanation
- Contribution of Electrons: In a coordinate bond formation, one atom donates a pair of electrons to another atom.
- Sharing of Electrons: The pair of electrons contributed by one atom is then shared between both atoms, creating a strong electrostatic force that holds the atoms together.
- Formation of Covalent Bond: This sharing of electrons leads to the formation of a covalent bond, where both atoms achieve stability by completing their outer electron shells.
- Characteristics of Coordinate Bond: The bond formed in this manner is known as a coordinate bond or dative bond. It is represented by an arrow pointing from the donor atom to the acceptor atom, indicating the direction of electron transfer.
- Examples: One common example of a coordinate bond is found in the formation of metal complexes, where a metal ion accepts electron pairs from ligands to form stable coordination compounds.
In conclusion, during a coordinate bond formation, a pair of electrons is contributed by one atom and shared by both atoms, leading to the formation of a strong covalent bond.

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescence microscopy.Q. Wavelength of electron as wave at accelerating voltage 200 keV is
