<span>The </span>elements are arranged<span> in order of increasing atomic number. Vertical columns(called groups) contain </span>elements with similar properties. Horizontal rows called periods elements with<span> the same number of atomic orbitals(That's why Hydrogen and Helium are separated from the rest of the table).
Hope this helps:)</span>
The nitrogen has been reduced or has undergone reduction and it has gained one electron
<span>An ionic bond is the transfer of electrons and a covalent bond is a sharing of electrons
Happy studying! ^_^</span>
The photoelectric effect occurs when light shines on a metal. ... Light of any frequency will cause electrons to be emitted.
Explanation:
(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.
