Here’s the complete list of 60 key terminologies for GCSE Chemistry:Atom: The smallest unit of an element, consisting of protons, neutrons, and electrons.Element: A substance made of only one type of atom.Compound: A substance formed when two or more elements chemically combine.Molecule: A ...

The elements that are formed naturally bynuclear fissionor through the intentional synthesis in nuclear reactors or particle accelerators are calledRadio Active Elements. All elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. The increasing...
All the terms related should be briefly interpreted in English and Chinese. Thank you!Atomic Structure (原子结构)Atom (原子): The basic unit of a chemical element.Nucleus (原子核): The central part of an atom containing protons and neutrons.Proton (质子): A subatomic particle with a ...
force acts between the protons and neutrons, irrespective of the charge and it’s always strongly attractive. However, it has limitations of range. So, in the nucleus, there is a constant tussle between the repelling electromagnetic coulomb force of protons and the attractive strong nuclear force...
Elements Elements are the building blocks used to make up every substance in the world and cannot be broken down into anything simpler Each element is made of the same type of atom Compounds A compound is made when atoms of different elements join together ...
All atoms contain components called subatomic particles. Neutrons are neutral particles that are found in the nucleus of the atom along with the positively charged protons. The number of protons determines the element identity of the atom, and neutrons help determine the particular isotope of the at...
* Transient Solar System Events: The many unexpected transient elements in our solar system including changes on the Moon's surface, changes in Saturn's rings (see below), and the lifespan of our short-period comets which last only thousands, and not millions, of years because of the ...
Synthetic elements are man-made elements. They do not occur in nature. To find out more about these elements, read on...
total number of protons in an atom is called the atomic number. the sum of the number of neutrons and protons is known as the mass number. in an atom, the number of protons is always equal to the total number of electrons which makes it neutral due to equal and opposite charges of ...
