Answer:
(4) The physical and chemical properties of these minerals determine how humans use them.
Explanation:
All the materials and the metals found on earth shows certain characteristics naturally or in their physical state. These physical characteristics can be their look, their structure, their color, strength, melting point, boiling point, density, etc.
And chemical properties of the metals are defined as those characteristics or features of the metals that it exhibits when these metals reacts chemically.
The physical properties as well as the chemical properties distinguishes each metal from each other. These properties determines how people use these metals in their life.
- Dmitri Mendeleev- arranged elements according to their
atomic mass
- Johann Wolfgang Dobereiner-created groups of three elements,
each based on similar properties
- John Newlands-used patterns to predict undiscovered
elements
- Antoine Lavoisier-divided elements into four categories
Explanation:
The periodic table or the table depicting the arrangement of various elements has a long history. Several of the scientist starting from Lavoisier to Mendeleev contributed to the table in their might. The present table has been an evolution of the previous tables over their shortcomings.
Some of the notable contributions include-
- Mendeleev- Mendeleev arranged the elements in order of atomic mass rather than atomic mass. Through this, he also discovered new elements.
- Newlands- He formulated the Newland law of octaves similar to musical notation.
- Lavoisier- Lavoisier divided the elements into various categories and also defined elements.
- Dobereiner- He formulated the triad law which encapsulated that certain group of elements showed similar properties, hence can be grouped together.
