Valence electrons in an atom are the electrons (normally in the outermost shell) that can be shared or transferred to form bonds. In fact, in an atom, the inner electrons (beyond the outermost shell) are unusable and do not directly determine the chemistry of the elements.Answer ...
To determine the number of valence electrons in the atom of an element A with atomic number 20 and to identify its valence shell, follow these steps:Step 1: Write the Electronic Configuration The atomic number of element A is 2

1 An atom of an element has an atomic number of 6 and a mass number of 12.(a)Using this information, complete the table to show the numbers of protons,neutrons and electrons in one atom of this element.(2)number of protons number of neutrons number of electrons(b)The Periodic Table ...
Valence electrons are the electrons that are located in the outermost shell of an atom. In other words, these are the electrons that can be gained or lost during a chemical reaction. Where Are Valence Electrons? Irrespective of the type of chemical bond between atoms, be it an ionic, c...
called quantum numbers. Each of these numbers corresponds to a different attribute of the orbital, which allows physicists to identify the exact orbital they want to discuss. They are also related to the total number of electrons an atom can hold if this orbital is its outer, or valence, ...

An oscillatory dependence of the properties on the number of valence electrons per atom was observed. The constituents of the alloys were mainly non-transition metals: for the A-elements Ca, Y, La and Th and for the B-elements In, Sn, Tl and Pb. The results can be explained by taking...
