He does not form a chemical compound. The He2 molecule is not knon. The He2+ cation has a very transient existence and has a reportedly very short bond length of approximately 0.75 Angstrom.

How do the LCAO model explain the fact that He have a bond energy of 1e-3 and average bond length of 50 angstrom?

LCAO linear combination of atomic orbitals is a technique used in molecular orbital theory. He refers to an ATOM helium. Atoms do not have bond energy. The question as asked is meaningless


What is the area measured by an angstrom?

The angstrom is an internationally recognized unit of length equal to 1 x 10^-10 meters, or 0.1 nanometer. The angstrom is used is physics, chemistry and biology to describe the length of small particles such as atoms and molecules, as well as wavelengths.


Is Angstrom a unit for measurement of length?

No all distances are measured in metres. Large distances in multiples of a metre, and small distances in fractions of a metre. Radii of atoms fall between 30 and 300 picometres. A picometre, pm, is 10−12 metres.


What is a measure of the force of gravity acting on the object?

The word is "angstrom," not "anstrom." An angstrom is a unit of length - a very, very small unit. One angstrom is ten to the minus ten meters, which is one ten-billionth of a meter. Angstrom units are often used in measurements such as the wavelengths of various kinds of light, from say infrared to ultraviolet.


What is the measure of the force of gravity acting on a n object?

What is difference between angstrom and astronomical unit?

An angstrom is a unit of length equal to one ten-billionth of a meter, commonly used to measure atomic distances. An astronomical unit is a unit of length based on the average distance between the Earth and the Sun, approximately 93 million miles, often used to measure distances within our solar system.


How many angstroms in 1 meter?

An angstrom = 1 x 10-10 meters so in one meter there would be 1 x 1010 angstroms.


Does Angstrom measure the speed of ship?

No, Angstrom is a unit of length used to measure very small distances, such as the size of atoms and molecules. The speed of a ship is typically measured in units like kilometers per hour or nautical miles per hour.


Explain how to calculate average speed?

Average speed = d/t (distance covered in some period of time) divided by (the length of time to cover it)


What is the unit of measuring wave length of light?

nanometer


What are the bond angles for O2?

The bond in N2 dinitrogen is a triple bond, with a length of 109.76 pm. An indicator of the length of a single N-N bond is given by hydrazine. H2NNH2, where the N-N is 145pm, this indicates the shortening in N2 due to the extra pi bonds.


Is the length of a pencil more or less then a meter explain?

An average pencil is about one sixth of a metre. That means six of them will fit in one metre length
