Answer:

-The mass of the reactants (carbon dioxide and oxygen) is the same as the mass of the products (water and sugar).

how do atoms combine to form extended structure?

Answers

Answer:

lose or share electrons in such a way that the outer shells become chemically complete

Explanation:

Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
