Elements may be classified as either metals or nonmetals, based on their properties.
Here's a look at the differences between the metals and nonmetals.
Most elements are metals. On the Periodic Table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine and radon. These elements and those to the right of them are nonmetals. Elements just to the left of the line may be termed metalloids or semimetals and have properties intermediate between those of the metals and nonmetals. The physical and chemical properties of the metals and nonmetals may be used to tell them apart.
Metal Physical Properties
lustrous (shiny)
good conductors of heat and electricity
high melting point
high density (heavy for their size)
malleable (can be hammered)
ductile (can be drawn into wires)
usually solid at room temperature (an exception is Mercury)
opaque as a thin sheet (can't see through metals)
metals are sonorous or make a bell-like sound when struck
Metal Chemical Properties
have 1-3 electrons in the outer shell of each metal atom
corrode easily (e.g., damaged by oxidation such as tarnish or rust)
lose electrons easily
form oxides that are basic
have lower electronegativities
are good reducing agents
Nonmetals
Nonmetal Physical Properties
not lustrous (dull appearance)
poor conductors of heat and electricity
nonductile solids
brittle solids
may be solids, liquids or gases at room temperature
transparent as a thin sheet
nonmetals are not sonorous
Nonmetal Chemical Properties
usually have 4-8 electrons in their outer shell
readily gain or share valence electrons
form oxides that are acidic
have higher electronegativities
are good oxidizing agents

How do most periodic tables differentiate between metals and nonmetals?
Most periodic tables differentiate between metals and nonmetals by placing the metals on the left and in the middle of the table, and the nonmetals on the right. The dividing line between metals and nonmetals is often marked by a zigzag line that separates the two categories, with elements to the left being metals and elements to the right being nonmetals.
What are two types of elements in the periodic table?
Two types of elements in the periodic table are metals, which are typically shiny and good conductors of heat and electricity, and nonmetals, which are generally poor conductors of heat and electricity.
Where are nonmetals an metalloids located?
Nonmetals and metalloids are located on the right side of the periodic table. Nonmetals are found on the right side of the dividing line between metals and nonmetals, while metalloids are found along the dividing line.
What are the two main types of element?
The two main types of elements are metals and nonmetals. Metals typically have properties like being good conductors of electricity, while nonmetals are typically poor conductors and can be found in various states like gases or solids.
What is a element with two or more nonmetals bonded together called?
A molecule is formed when two or more nonmetals bond together. Molecules are the smallest unit of compounds formed by nonmetals.
Why do metals and non metals usually form ionic compounds where as two bonded nonmetals are never ionic?
Metals tend to lose electrons to achieve a stable configuration, while nonmetals tend to gain electrons. This electron transfer results in the formation of ionic compounds between metals and nonmetals. In contrast, two bonded nonmetals typically share electrons to achieve a stable electron configuration, leading to the formation of covalent bonds rather than ionic bonds.
What are the three classes of elements?
The three classes of elements are metals, nonmetals, and metalloids. Metals are typically shiny, solid at room temperature, and good conductors of heat and electricity. Nonmetals are usually dull in appearance, brittle, and poor conductors of heat and electricity. Metalloids have properties that are intermediate between metals and nonmetals.
What are 2 charactistics of non-metals?
Metals and Nonmetals have specific characteristics. Two characteristics of Nonmetals are typically brittle and do not shape easily, and they do not conduct heat or electricity well.
How do most periodic tables differentiate between metals and nonmetals?
Most periodic tables differentiate between metals and nonmetals by placing the metals on the left and in the middle of the table, and the nonmetals on the right. The dividing line between metals and nonmetals is often marked by a zigzag line that separates the two categories, with elements to the left being metals and elements to the right being nonmetals.
What are two groups of elements?
There are three types of elements: metals, metalloids, and nonmetals. Most elements are metals.
What kind of elements form ionic bonds with nonmetals?
Metals typically form ionic bonds with nonmetals. Metals tend to lose electrons to achieve a stable electron configuration, while nonmetals tend to gain electrons. This transfer of electrons results in the formation of ionic bonds.
What are two major categories of elements split into?
The two major categories of elements are metals and nonmetals. Metals are typically shiny, malleable, and good conductors of heat and electricity, while nonmetals are usually dull in appearance, brittle, and poor conductors.
What are the two main categories of elements on a periodic table?
actually, there are 3... metals, metalloids, and nonmetals.but, the 2 biggest are metals and nonmetals.
The atoms in one group can form compounds with the atoms in the other group but not with atoms in their own group which atoms are in each group?
The atoms in one group are metals and the atoms in the other group are nonmetals. Metals form compounds with nonmetals by transferring electrons, while nonmetals form compounds with other nonmetals through sharing electrons.
What are the two division of periodic table?
The two main divisions of the periodic table are the metals on the left side and the nonmetals on the right side. The metals are further divided into alkali metals, alkaline earth metals, transition metals, and other metals, while the nonmetals include elements such as carbon, nitrogen, oxygen, and the noble gases.
Why don't non polar covalent bond cant possible for metals and non metals?
Non-polar covalent bonds occur between two nonmetals that have similar electronegativities. Metals and nonmetals have significantly different electronegativities, so they tend to form ionic bonds or polar covalent bonds instead of non-polar covalent bonds. Metals usually donate electrons to nonmetals to achieve stability, resulting in the formation of ionic bonds or polar covalent bonds due to the difference in electronegativities.
What is the name of light metals from water?
Water (H2O) is composed from oxygen and hydrogen - two nonmetals.
