Honshu is the largest of the four main islands and is approximately equal in area to United Kingdom. Tokyo is one of the five largest cities of the world.

The number of bonds between a pair of atoms is called the bond order.

Bond orders can be calculated from Lewis structures, which are the heart of the valence-bond model. Oxygen, for example, has a bond order of two.

When there is more than one Lewis structure for a molecule, the bond order is an average of these structures. The bond order in sulfur dioxide, for example, is 1.5  the average of an S-O single bond in one Lewis structure and an S=O double bond in the other.

In molecular orbital theory, we calculate bond orders by assuming that two electrons in a bonding molecular orbital contribute one net bond and that two electrons in an antibonding molecular orbital cancel the effect of one bond. We can calculate the bond order in the O₂ molecule by noting that there are eight valence electrons in bonding molecular orbitals and four valence electrons in antibonding molecular orbitals in the electron configuration of this molecule. Thus, the bond order is two.

A manometer is used to measure a pressure difference between two points.

In computing, memory refers to the computer hardware integrated circuits that store information for immediate use in a computer.

Most semiconductor memory is organized into memory cells or bistable flip-flops, each storing one bit (0 or 1).

Energy is measured in units called Joules.

Joule is unit of work or energy in the International System of Units (SI) which is equal to the work done by a force of one newton acting through one metre.

1 Joule  =  10⁷ ergs or 0.7377 foot-pounds.
