classify the elements based on their properties

$\huge\color {pink}\boxed{\colorbox{black} { ANSWER}}$

Elements are typically classified as either a metal or nonmetal, but the dividing line between the two is fuzzy. Metal elements are usually good conductors of electricity and heat. The subgroups within the metals are based on the similar characteristics and chemical properties of these collections.

The English chemist John Newlands (1838–1898), hypothesizing that the chemistry of the elements might be related to their masses, arranged the known elements in order of increasing atomic mass and discovered that every seventh element had similar properties

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.

Answer 2

Answer:

On the basis of their properties elements are classified into three types

1) Metals

2) Non- metals

3) Metalloid

Explanation:

• On the basis of their properties elements are classified into three types

1) Metals

1) Metals 2) Non- metals

1) Metals 2) Non- metals 3) Metalloid

1)Metals-

• These are the positively charged elements .
• These are having shiny surface and good conductor of heat and electricity.
• They are lustrous.
• Form cation by loosing one electron.
• Form the basic oxides and hydroxide .
• Present at the left side of the periodic table.
• Example- sodium , Potassium etc

2)Non - Metals -

• Non metals are generally those elements which lacks the pre- dominance of metals.
• These are brittle in nature.
• Non - lustrous and they cannot be polish (except iodine )
• These are good insulators of heat and electricity.
• Form anion by gaining electron.
• Example - Carbon, Nitrogen etc

3) Metalloid-

• Elements which contains or exhibits both properties of metals and non- metals .
• They are semi- conductive in nature.
• Examples- Germanium (Ge), Arsenic etc
• SPJ3
