So on the first energy level, we have 1s2, because it has at least as many electrons as helium. Okay, so we know oxygen has 8 electrons, and only two electrons can exist in each orbital. This means thatĪnd if you were to go a step farther with helium, you would get 1s2, because it has two electrons in that s orbital. Hydrogen has an electron configuration of 1s1. Their electron configuration is determined by the number of electrons their neutral form has and the orbitals in which those electrons exist. The numbers that you are talking about are called electron configurations, and each element has its own unique one. And I really don't know much about f orbitals (I've never had one that large) but I believe there can be seven d orbitals are a really complicated shape and there can be up to five. p orbitals are kind of dumbbell shaped and there can be up to three of them at each energy level. s orbitals are sphere shaped, and there can only be one at each energy level. Okay, now, there are different types of orbitals that each take different shapes. Finally, each orbital can hold only two electrons and no more. The farther out the orbital from the nucleus, the more energy the electron has. Each orbital also represents a different energy level.

For example, if the orbital is in the shape of a sphere, the electron can exist in any point within that sphere, but it cannot go outside that sphere. An orbital is basically a given space that an electron can exist in. You may already know some of this stuff but I'll go over all of it anyway.īasically, every atom has orbitals around their nucleus. You can effortlessly find every single detail about the elements from this single Interactive Periodic table.Okay, this is a long, long explanation. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ).

Free Gift for you: Interactive Periodic Table The alloy formed by mixing antimony and lead is used in manufacturing battery components, cable sheathing, etc.The compounds of antimony are used in manufacturing of glass, paints, ceramics, etc.Antimony is a metalloid and hence it is used in semiconductor devices like diodes, infrared detectors, etc.When antimony is heated in air, it forms antimony trioxide.Antimony can be dissolved in oxidizing acids like sulfuric acid or nitric acid.When antimony is reacted with acids, it does not easily dissolve into it.The black allotrope of antimony easily gets corroded when kept open in air. When antimony is kept open in air, it does not react easily.Chemical properties of AntimonyĬhemical properties of antimony are mentioned below. Antimony has many isotopes, but out of them the most abundant isotope is 121Sb (around 57%).The crystal structure of antimony is Rhombohedral.The melting point of antimony is 630.6 ☌ and its boiling point is 1635 ☌.

The atomic mass of antimony is 121.76 u and its density is 6.7 g/cm 3.Antimony is hard and brittle which can not be malleable.Antimony is a poor conductor of heat and electricity at room temperature.Antimony is solid at STP and has a silvery grey metallic lustre.Physical properties of antimony are mentioned below. The physical and chemical properties of antimony element are mentioned below. In ancient times, antimony was used as a reflecting surface in mirrors.China is the leading producer and supplier of antimony in the world (more than 80%).The abundance of antimony in the earth’s crust is estimated to be 0.2 to 0.5 part per million.Antimony is very rarely found in its pure form, but it is mostly found from the mineral stibnite.The name antimony was derived from the Greek words “anti” and “monos” which means a metal that is not found alone.Interesting facts about antimony element are mentioned below. So the last electron of antimony enters the p-subshell or p-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of antimony is 4d 10 5s 2 5p 3. How can you determine the blocks-wise position of elements? Before knowing this reason, first of all I want to ask you a simple question.
