Introduction: An atom consists of electrons (e), protons (p) and neutrons (n). Different atoms have specific numbers of electrons, protons and neutrons. The electron and proton are negatively and positively charged respectively. Neutron has no charge. Nucleus of an atom contains protons and neutrons that constitute the mass of an atom. Electrons revolve around the nucleus in their orbit. The atomic number of an element is the number of protons in the nucleus of its atoms. In a neutral atom, the number of protons and electrons is equal. Thus, the number of electrons present in a neutral atom is equal to its atomic number. An isotope of an atom differs from neutron numbers and therefore by mass.

- Which element has only one proton?arrow_forwardVisit this website (http://openstaxcollege.org/l/ptable) to view the periodic table. In the periodic table of the elements, elements in a single column have the same number of electrons that can participate in a chemical reaction. These electrons are known as valence electrons. For example, the elements in the first column all have a single valence electron—an electron that can be donated in a chemical reaction with another atom. What is the meaning of a mass number shown in parentheses?arrow_forwardif 10 magnesium atoms and 10 chlorine atoms were allowed to bump into each other, could they combine to form a substance? How many molecules made? Would there be any atoms left over? Which ones? How many?arrow_forward
