Definition of Atom and What Makes It Different from Compounds – If you split particular matter repeatedly until you find it is cannot be divided any longer, you will get something called as atom. That is the definition of atom. In the nutshell, atom is the smallest unit of matter that cannot be divided anymore. The atom itself can take any different forms, such as solid, gas, liquid, and plasma. Since it cannot be divided anymore, it is only logical if the size of atom is at small size. In average, the size of this entity is roughly 100 picometers. A picometer is a number that you get after dividing a meter ten billion times.
Understanding the Definition of Atom
After talking about atom size based on the definition of atom, it is interesting to point out that everything is made of atom. Despite its small size, every matter consists of atom. An atom itself consists of three important elements. The core of an atom is called as nucleus. The structure of nucleus consists of both neutron and protons. Several electrons orbit this nucleus in particular manner based on their place in the periodic table. What are electrons and proton definition? Here is the brief definition about it.
Proton definition is often associated with electrical property it has to offer. Proton contains positive electrical property. As previously mentioned, proton can be found on the same spot as neutrons. Every atom with nucleus is packed with protons and neutron. In most case, the amount of proton that can be found in an atom is highly influenced by atomic number of particular atom in the periodic table. In order to keep the atom in stable condition, both electron and proton of an atom are often the same with slight difference.
That is the proton definition. Now we need to talk about the definition of electron. In contrast to proton, electron has negative electric property. Electron can be found orbiting nucleus containing neutron and protons. The movement of this orbit follows particular rule with complicated detail. When an atom released electron and accepted by nearby atom, it will trigger electric charge. Therefore, the electricity is basically movement of electron. People can create it with one way or another by simply stimulating electron on a particular atom to move to another atom. By the definition of electron, the amount of electrical current generating from this process is heavily influenced by the amount of electron moving between atoms.
Since the atomic number of an atom can be different from one atom to another, the number of electron in it can be different as well. If you want to know some atom examples, all you need to do is looking at periodic table. They will have specific atomic number. Some of atom examples are including Oxygen, potassium, carbon, and many more. If two or more of them are binding with each other, then they might create something called as compound. One of the most popular compounds is water. A compound of water consists of two hydrogen atoms and one oxygen atom.
That is the brief definition of atom. From the explanation above, you can tell that atom can be easily found anywhere. Every matter consists of countless amount of atom. Since atoms are smallest unit of a matter, they obey specific role. After reading this article, you might wonder why you need to know about why you need to know about it.
In order to make it simple, definition of atom only covers about the structure of atom. It is interesting to point out that study of atom is not exclusively for physics. People who study chemistry often learn about it as well. Understanding about atom examples, including definition of electron and proton will help to determine how a matter will react to other matter when they are interacting.
