- Ionization Enthalpy: Ionization enthalpy decreases with increase in the size of the central atom. Therefore, it decreases as we move from Oxygen to Polonium since the size of the atom increases as we move down.

‘Dust of Snow’ is a beautiful poem written by Robert Frost. This poem conveys that even a simple moment has a large significance. The poet mentioned crow and hemlock tree in this poem. Crow signifies his depressive and sorrowful mood and hemlock tree is a poisonous tree. Both these signify that the poet was not in a good mood and so he describes the dark, depressive and bitter side of nature to present his similar mood.
The poet says that once he was in a sad, depressive mood and was sitting under a hemlock tree. A crow, sitting on the same tree, shook off the dust of snow, small particles of snow that remained on the surface after the snowfall, on the poet. This simple action changed the poet’s mood. He realised that he had just wasted a part of his day repenting and being lost in sorrow. But the change in his mood made him realise that he should utilize the rest of the day in some useful activity. His sorrow was washed away by the light shower of dust of snow. His spirit was revived and he got ready to utilize the rest of the day.

In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculation, data processing, and automated reasoning.Algorithms resemble recipes. Recipes tell you how to accomplish a task by performing a number of steps.
For example, to bake a cake the steps are: preheat the
oven; mix flour, sugar, and eggs thoroughly; pour into a baking pan; and so forth.

There are no batteries that actually store electrical energy; all batteries store energy in some other form. ... The space between the electrodes is filled with an electrolyte--an ionic liquid that conducts electricity. One electrode--the anode--permits electrons to flow out of it. The other--the cathode--receives them. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
