Answer to Question #41564 in Other Chemistry for hamdan744
1) Discuss how are elements, compounds, neutrons, protons, atomic number ,mass number and isotopes are related under structure and bonding
(Information should include the interrelationship between the structure and bonding in elements all in detail)
An atom is the smallest unit of matter that retains all the chemical properties of an element. An atom is composed of two regions: the nucleus in the center of the atom, which contains protons and neutrons, and the outermost region of the atom, which holds its electrons. Atoms consists of protons, electrons, and neutrons. The only exception is hydrogen (H), which is made of one proton and one electron with no neutrons. A proton is positively charged whereas a neutron is uncharged. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Atoms of each element contain a characteristic number of protons and electrons. The number of protons determines an element’s atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess. Together, the number of protons and the number of neutrons determine an element’s mass number. Since an element’s isotopes will have slightly different mass numbers, scientists also determine the atomic mass, which is the calculated mean of the mass number for its naturally occurring isotopes.
