Answer:

a. Chemical bonds.

Explanation:

Hello,

In this case, it is necessary to know that when two elements are not stable by their own they should bond with an other atom of the same element via chemical bonds whereby the valence electrons act as bridges connecting the atoms. Some examples are diatomic-gaseous hydrogen, oxygen, nitrogen, chlorine, iodine, fluorine and bromine. Moreover, such chemical bonding is represented by lines binding the elements as shown on the attached picture.

Best regards.

Bogdan [553]

Answer: pure substances.


Explanation:


The given substances are:

  • H₂O₂
  • Li
  • NaCl
  • O₂

All what surrounds us, which has mass and occupies spaces, is matter. There are two kind of matter: pure substances and mixtures.


Pure substances have a uniform and constant composition. On the other hand, mixtures are combinations of two or more pure substances in  any arbitratry ratio.


Pure substances may be elements or compounds. The elements are the substances conmposed by one only kind of atom. In the list of substances given, Li and O₂ are elements: all the atoms in Li are lithium, and all the atoms in O₂ are oxygen atoms.


Compounds are the chemical combination of two or more different kind of atoms. In the given list H₂O₂ and NaCl are compounds. As you see, H₂O₂ contains atoms of hydrogen and oxygen, chemically bonded, in a fixed ratio (2 atoms of hydrogen by 2 atoms of oxygen). And NaCl has atoms of Na (sodium) and Cl (chlorine), chemicaly bonded, in a fixed ratio (1:1).


There are only 118 known elements and you can find them in any modern periodic table. Therer are virtually infinitely many compounds since many different combinations of the elements can be attained.


Elements and compounds have in common that they are classified as pure substances.
