Answer: Heres my Answer
Explanation: A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
The question is incomplete, the complete question is given below:
Which of the following best describes a molecule?
a unit made of different kinds of elements
a unit made of only one kind of element
a unit made of two or more atoms
a unit made of a single atom
Of the mentioned options, the statement that best describes a molecule is that it is a unit made of two or more atoms.
It is the smallest particle in a chemical compound or element, which possesses similar properties with that of the compound or element. The molecules are formed of atoms, which are held together with the help of chemical bonds.
These bonds develop as an outcome of the exchange or sharing of electrons between the atoms. The atoms of elements bond easily with other atoms to produce molecules. The molecules can differ largely in complexity and size.
Thus, the correct statement is that it is a unit made of two or more atoms.
