Answer 2

Answer:

Explanation:

An element is the simplest form of matter that cannot be split into simpler substances or built from simpler substances by any ordinary chemical or physical method. There are 118 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids based on their properties, which are correlated with their placement in the periodic table.

Metallic Elements Nonmetallic elements

Distinguishing luster (shine) Non-lustrous, various colors

Malleable and ductile (flexible) as solids Brittle, hard or soft

Conduct heat and electricity Poor conductors

Metallic oxides are basic, ionic Nonmetallic oxides are acidic, covalent

Form cations in aqueous solution Form anions, oxyanions in aqueous solution

Metals

With the exception of hydrogen, all elements that form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements with relatively low ionization energies. They are characterized by bright luster, hardness, ability to resonate sound and are excellent conductors of heat and electricity. Metals are solids under normal conditions except for Mercury.
