WebValency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element is always a whole number. Some elements exhibit more than one valency, i.e., they have variable valency. WebThe elements which have a tendency to gain electrons are known as non-metals. Since sodium has a valency of +1 means it is losing one electron to acquire the Nobel gas configuration therefore it is a metal. (4) Name of the element: The name of the element is Sodium.
