Can an atom make 8 bonds? Yes, there are coordination complexes of large elements which have coordination numbers greater than eight. Some examples are: [ReH9]2− with a tricapped trigonal prismatic structure. The nine hydride ligands are small enough to fit around the relatively large rhenium atom fairly easily. Is there a double bond in water? […]

How does light interact with eyes? Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The […]

What happens if you put a conductor in a capacitor? Originally Answered: When a conductor is placed between the plate of a capacitor, then what is the effect on its capacitance? Inserting an otherwise unconnected conductor introduces an isopotential surface. If it is inserted in an existing isopotential plane, it has no effect. Otherwise the […]

Why is the North Star in the West? The North Star, also known as Polaris, is known to stay fixed in our sky. Earth’s spin causes the sun in the daytime – and the stars at night – to rise in the east and set in the west. But the North Star is a special […]

However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. Technically, it’s considered an exosphere. How does […]

What is the difference between sampling with replacement and without replacement? What’s the Difference? When we sample with replacement, the two sample values are independent. Practically, this means that what we get on the first one doesn’t affect what we get on the second. In sampling without replacement, the two sample values aren’t independent. What […]
