Metalloids can be defined as chemical elements whose physical and chemical properties fall in between the metal and non-metal categories. Boron, germanium, silicon, antimony, arsenic, tellurium and pollanium are the seven most widely recognized metalloids. It can be noted that all seven of these elements can be found on the regular periodic ...
Ans: Metals, non-metals, and metalloids can be classified as elements. Metals are great heat and electricity conductors and are malleable (can be hammered into sheets) and ductile (can be drawn into wire). Typical nonmetals have a dull appearance, relatively low melting points, boiling points, and densities, and are poor conductors of heat and ...
Non-metals are such elements which have 4,5, 6 and 7 electrons in their outermost shell. Examples of non-metals are carbon, oxygen chlorine etc. Metals are such element which have generally 1,2,3 valence electrons. Example of some metals are Sodium, Potassium, Copper etc.
A metal is a component, material, or alloy that is usually solid, transparent, shiny, and has good conductivity in terms of electrical and thermal. Metals are usually malleable, which ensures that they can be indefinitely hammered or pressed without fracturing or cracking, as well as fusible or ductile. Q3.
1.9. Some of the trends in the modern periodic table with respect to group 15 elements of the p-Block elements are discussed below. 1. Electronic Configuration. The valence shell electronic configuration plays a major role in how an element behaves. The valence electron shell configuration of group 15 elements is ns 2 np 3.
Difference Between Metals and Nonmetals- The elements present on the extreme right side of the periodic tables are non-metal, About 80 of the 105 elements in the periodic table are regarded as metals.

Metals are the electropositive element that tends to donate electrons and form positive ions and become stable. For example: Na → Na + + e –. Metals also generally have certain distinguishing physical properties that make them easy to identify and classify. Some main physical properties of metals are; They have lustre and a metallic appearance.
There are 118 known elements, 92 of which are derived naturally and the remaining 26 are created artificially in laboratories. These elements are classified into three groups based on their physical and chemical properties: metalloids, metals, and non-metals. Metals are elements that are typically hard due to a strong metallic bond between the ...
Periodic Table of Elements (Interactive) [PDF] - This Interactive Periodic Table is a tabular arrangement of the chemical elements, organized based on chemical element names, symbols, atomic masses, electron configuration and other chemical properties.
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons.
