What is the atomic mass of an electron? What is the difference between atomic structure and crystal structure? What chemical element has atomic number 118? What chemical element has atomic number 35? What is atomicity in chemistry? What atomic particle in an atom is the same for each element...
Every element has a chemical symbol, e.g. the symbol for the element sodium is Na. Each element also has an Atomic Number and a Mass Number. Together, these describe the atoms of that particular element. It is possible to describe all known elements in a single table - which is called...
Atoms themselves can be 'broken down' into smaller sub-atomic particles (protons, neutrons and electrons) - the amounts of these (particularly the number of protons) define each element. For example, in their un-ionised form, the element carbon is made entirely from carbon atoms, which...
Elements in Chemistry | Overview & Examples from Chapter 1 / Lesson 1 326K Learn basic information about what an element is, what they are made of, how and why they are different, and how scientists have organized them into the periodic table. Related...
Learn about atoms, the fundamental unit of matter in the universe. Discover the different parts of an atom, such as the nucleus, proton, neutron, and electrons. Also, explore atomic bonding, the way atoms join together to form molecules. ...
is assigned an atomic number which tells the number of protons in the atom. Normally, an atom has the same number of positive particles (protons) and negative particles (electrons). So the number of protons is identical to the number of electrons, and both are identical to the atomic ...

An atomic force microscope (AFM) is an extremely precise microscope that images a sample by rapidly moving a probe with a nanometer-sized tip across its surface. This is quite different than an optical microscope which uses reflected light to image a sample. An AFM probe offers a much higher...
