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?

If you are referring to the periodic table, then metals and non-metals, though if that is the case I should remind you that metalloids are also a category. Though if you were asking more broadly about molecules, as this category would suggest, you're probably looking for organic and inorganic.


Is alkalin earth metals metalliods or nonmetals?

Alkaline earth metals are neither metalloids nor nonmetals; they are classified as metals. This group, which includes elements like magnesium and calcium, is characterized by their shiny appearance, good conductivity of heat and electricity, and the ability to lose two electrons to form positive ions. Unlike metalloids, which have properties of both metals and nonmetals, alkaline earth metals exhibit distinctly metallic properties.


Where are nonmetals an metalloids located?

Metals are located on the left of Mendeleev's Periodic Table, and non-metals are located on the right. Metalloids are in-between the two. If you look at the table you'll see it 's skinnier in the middle (I can't think of a better word). The entire skinny part and the two columns to the left of it are all metals. Everything else to the right is either metalloids or non-metals.


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.

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.

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?

Metals can form ionic bonds with non-metals. Non-metals can form bonds with each other covalently. Two metals cannot form compounds with each other.AnswerIf you mean group x can form compounds with group y but not with atoms in group x. Then group x is the metals and group y is the non-metals.The question is a little confusing as group one and group two mean somthing in chemistry. The chemistry generally group one and two is used to refer to two different types of metals called the alkali metalg and the alkaline earths. They are in these groups on the periodic table.


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.


The two major categories of chemical elements are?

Metals and nonmetals. There are also metalloids as well though.
