WebElements that gain electrons (while forming an electrovalent bond) or share electrons (while forming a covalent bond) are known as non-metals. In their outermost shell, they frequently include 4, 5, 6, or 7 electrons. Non-metals are substances lacking all the qualities of metals. A non-metal is an element that often conducts heat and ... WebHelium is a non metal. There are many reasons supporting this,some of them are: (a) It is unable to donate an electron,just because of its inert (unable to react) nature. (b) It has lowest melting and boiling points of all elements. An intersting fact about helium: chip and scratch nampa
