bonds between two of the same atoms, such as nitrogen (N2) or oxygen (O2) have an even distribution of electrons, making the atoms non-polar. Other molecules that use more than two of the same atom, such as ozone (O3), are also non-polar. Polar atoms occur when different atoms are ...
An Atom, being very small in size and mass, is not easy or convenient to measure with a normal measuring unit. Previously, scientists used experiments to measure the mass of an atom in relation to another. A unit of mass used to describe the mass of the atomic and subatomic particles is...

Just like the other prompts, you describe the intent of the interaction to the API. In this case, "a conversation." This input prepares the API to process subsequent input according to the initial intent. Tell the API how to behave. A key detail in this demonstration is the ex...
Define the intent of the conversation. Just like the other prompts, you describe the intent of the interaction to the API. In this case, "a conversation." This input prepares the API to process subsequent input according to the initial intent. ...
How does the incident light that falls on an object affect the motion of electrons in the atoms of the object? Atoms are made up of . When temperatures are near absolute zero, what process causes atoms to begin to clump? Describe what are the properties of matter?
He used the term "dark matter" to describe the unidentified mass required to cause this surge in velocity. How did scientists discover dark matter? When astronomers began measuring the rotations of spiral galaxies in the 1950s and '60s, they made a puzzling discovery. They expected to see ...
How to find the momentum in an electron through the photoelectric effect How are OH- ions liberated during cyanohydrin formation? How does an electron being a particle possess a wave nature? Describe some experiments that would support the conclusion that t...
Describe the bond that holds the atoms in a water molecule together. How does a molecule differ from an atom? Why do atoms share electrons in covalent bonds? What is the arrangement of atoms within a molecule called? Which force binds atoms together to form molecules?
