Why everything in space has a near-about spherical shape?

While reading about solar system or space, have you not wondered why the planets or the stars are round and not cubes or cuboids or of variable shapes? Well here is the answer to you:


Space and time are not absolutes, meaning they are not phenomena that are fully unaffected. When matter enters into space, it curves space. We know that space has three dimensions (X-dimension, Y-dimension and Z-dimension). Though they appear flat in geometry, they actually curve up when matter enters into them. Let me give an analogy of water. Though it is not directly connected and the effects are different, still it may help you. When we drop a stone in water or enter into the bath, the stone or our body displaces the water. Does the water ever remain the same? No. Now in the same way, space does not remain the same but curves up. Gravity is a consequence of this phenomenon. Even if there is a single atom in space, the fact that it occupies space makes other particles gravitate towards it in the same way as the atom or atoms affect space. So that is why everything is circular in space as that is the way they affect space. That is an idea given in Einstein's Theory of General Relativity.

Group 14-16: Non metals ( Periodic Table #6)

Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well . Non-metallic elements are very brittle , and not malleable (i.e.cannot be rolled into wires or pounded into sheets). The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light . They have oxidation numbers of ±4, -3, and -2. The Non-Metal elements are: Hydrogen Carbon Nitrogen Oxygen Phosphorus Sulfur Selenium  Although five times more elements are metals than nonmetals, two of the nonmetals —hydrogen and helium—make up over 99 per cent of the observable Universe,  and one—oxygen—makes up close to half of the Earth's crust, oceans and atmosphere.   Living organisms are also composed almost entirely of nonmetals,  and nonmetals form many more compounds than metals CREDIT: wikiped...

Structure of atoms #2 : Electronic Configuration

Image
The arrangement of electrons in the various shells/orbits/energy levels of an atom of the element is known as electronic configuration. Bohr-Bury scheme Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable. 1 s t  energy level is K shell 2 n d  energy level is L shell 3 r d  energy level is M shell 4 t h  energy level is N shell and so on. Electronic configuration of an element Bohr and Bury Scheme - Important Rules 1. Maximum number of electrons that can be accommodated in a shell is given by 2n 2  where n=shell number For 1 s t  energy level, n = 1 Maximum number of electrons in 1 s t  energy level = 2n 2 2 x (1) 2 = 2 For 2 n d  energy level n=2 Maximum number of...
