Sodium is a metallic element that is a member of the alkali metals (Group 1A). It is a very reactive element that readily tends to lose its single valence electron by forming an ionic bond with nonmetals. Answer and Explanation: The answer is d. Cl. The reactivi...
What kind of group 1 atoms are the most reactive? What is an oxygen-18 atom? What is an atom? What is a metallic atom? What is a helium-4 atom with no electron? What is the most reactive nonmetal? What is in between the electrons and nucleus of an atom? What element will be mor...
to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. Most helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium ...

Oxygen is a chemical element with atomic number 8. It was discovered by Carl Wilhelm Scheele and Joseph Priestley around 1771 and was named by Antoine Lavoisier. It is a highly reactive nonmetal. By mass, it is a third-most abundant element in the universe, after hydrogen and helium. It ...
How are elements with nuclei heavier than those of hydrogen and helium formed? Classify each of these elements as representative, transition, or inner transition; state whether each is a metal or a nonmetal; and give its normal phase: (a) nickel (b) magne...
