### Why do pens Leak? See reasons

Capillary action is the ability of liquids to flow in a narrow space without the help of external forces such as gravity. This is actually why pens leak how the ballpoint pen works in the first place. When the tip comes into contact with the fabric, capillary action will tend to pull the ink out…

### All About Electronic configuration of atoms

Electronic configuration, also known as electron structure, is the arrangement of energy levels of electrons around the nucleus. As far as finer quantum mechanical models are concerned, the K-Q shell is subdivided into a set of orbits (see orbits), each of which can be occupied by no more than a pair of electrons. The electron…
