An element, simply put, is afundamental unit of matter that cannot be easily broken down. It consists of a specific number of protons and variable neutrons and electrons. All of matter is made of these 118 elements, combined in various ratios and kept in different states, like solids. Depen...
Mendeleev's periodic table of elements. The periodic table classifies all chemical elements according to their atomic number and chemical properties.

And then…… Dmitri Mendeleev devised a table in which to organize the elements (1869) in order to make them easier to study and understand. Each element has its own box full of information Element name Atomic number = # of protons Elements symbol Atomic mass= protons + neutrons ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...

The baseline of the neutronic periodic table of the elements is comprised of nine elements within the first twenty representative elements that have the same number of corresponding protons and neutrons in their nucleus, and establish a set of distinctive patterns of symmetry of nucleonic equilibrium,...
of their properties in a 3D space. It incorporates the basic interactions of HoloLens such as gaze and air tap. Users can learn about the elements with animated 3D models. They can visually understand an element's electron shell and its nucleus - which is composed of protons and neutrons. ...
4 The Periodic Table consists of elements arranged in order of increasing atomic number.(a)(i) What is meant by the term atomic number?(1) A the number of neutrons in an atom B the number of protons in an atom C the number of protons plus the number of electrons in an atom D the...
