2\. Above the symbol is the atomic number (Z) which is equal to the number of protons in the nucleus and the number of electrons in the electron cloud (given that the atom is neutral). For carbon Z=6. 3\. Below the symbol is the atomic mass. While this number is a weighted aver...

Avogadro, Amadeo (1776-1856) An Italian chemist who first stated the principle behind stoichiometry in 1811. Also seeAvoga...
The number of protons in the nucleus of an atom is called theatomic number. It is represented by the symbolZ Example: Helium has an atomic number of 2 since it has two protons in its nucleus. Lithium has an atomic number of 3 since it has three protons in its nucleus. ...

the difference is the number of protons found in the nucleus of the atoms. the number of protons makes each element unique, so they are organized by these numbers on the periodic table. the number of protons that are found in an atom of an element is called the atomic number. on the ...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? How to find the number of sides of a polygon using the given angle? How do you add coefficients with exponents?
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? How do I calculate the size of an exterior angle in regular polygons with 45 sides? How do I f...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
Atoms are predominantly made of electrons, neutrons, and protons. These particles may or may not exist depending on the nature of the atoms. Q3 What is an electron? The electron is one of the main subatomic particles in an atom whose electric charge is negative one elementary charge. These ...
Earth based experiments to create nuclear fusion require temperatures 10 times this which are produced in a plasma Torus, however because of the quantum probability that a protons ‘field of action’ can interfere with another protons field of action, then despite there not being enough energy for...
