Question

1. two - thirds of the modern periodic table is made up of metals. so when we think about the phrase “metallic properties” we think about how strongly these metals demonstrate these properties. similar to electronegativity, ionization energy and effective nuclear charge. metallic properties is a trend. (1) reaction to water is a chemical characteristic that mendeleev used to characterize elements. a. which elements showed the greatest...

analysis - metals, metalloids, and nonmetals

	metals	metalloids	nonmetals
ranked electronegativity (1 = least ; 3 = most)
ranked melting point (1 = least ; 3 = most)
ranked density (1 = least ; 3 = most)
luster	lustrous or dull	lustrous or dull	lustrous or dull
conductivity	good or semi or poor	good or semi or poor	good or semi or poor
ductility	ductile or not	ductile or not	ductile or not
malleability	malleable or not	malleable or not	malleable or not
brittleness	brittle or not	brittle or not	brittle or not
location on the periodic table

Explanation:

Step1: Analyze the problem context

The problem is about analyzing the properties of metals, metalloids, and non - metals, including concepts like ionization energy, electronegativity, and other metallic properties. This falls under the domain of Chemistry, which is a sub - field of Natural Science.

Step2: Determine the sub - field

Since the question is related to the properties of elements in the periodic table, chemical characteristics, and the work of Mendeleev in classifying elements, the sub - field is Chemistry.

Answer:

The sub - field that best applies to this problem is Chemistry (under Natural Science).
