periodic table metalsand nonmetals, and metalloids with names

The post-transition metals are those metals that come after the transition metals, but before the noble gases within a row. There are only eight of them, but they can take on some very unique properties, charges, and colors.

As of this writing, scientists have not isolated a stable element 119. Most elements were discovered naturally. However, heavier elements must be synthesized in a nuclear laboratory. Those larger than element 109 have all been formed and isolated this way.

These metals have very unique properties, owing to their f-orbital arrangements and unstable nuclei. As an example, uranium (U) is a part of this group.

Nonmetals on the periodic table

Depending on where you are in the universe, some are more prevalent. Here on Earth, elements like oxygen (O) and hydrogen (H) are common, but technetium (Tc) and nihonium (Nh) are rare.

Metalloids are those seven elements that make up the stair-step line on the periodic table, including boron and silicon. These elements have properties similar to both metals and non-metals.

The Periodic Table is integral to science education. In addition to the table itself, we provide learning resources and FAQs for teachers and students.

Only elements go onto the periodic table, and steel is an alloy, not an element. Steel is made from multiple elements. Its basic formula includes iron (Fe) with trace amounts of carbon (C).

Metalloids can take on either a positive or negative charge, depending on what other elements are around. These elements are particularly important for the electronic community.

The lanthanides and actinides refer to the two families of mostly radioactive metals in an off-shoot of the periodic table. Usually, they are shown as two rows on a separate section. The top row houses lanthanides, which are elements 57 – 70. The bottom row contains actinides, elements 89 – 103.

List ofmetals on the periodic table

The noble gases are the nonmetals that do no react with any element unless extreme conditions are imposed. They are the rightmost column on the periodic table. They usually do not form compounds, as they have a full octet.

On the periodic table, there is a family of eight elements known as the precious metals, including elements 44 – 47 like silver and 76 – 79 like gold. These metals are considered to be both very rare and of high value.

Transitionmetals periodic table

The transition metals include 34 metals in the middle of the periodic table. These metals are named this way, as they can take on many different charges, due to their valence electrons being in the d-orbitals. As a result, these metals tend to have a wide variety of colors and properties.

An element, simply put, is a fundamental unit of matter that cannot be easily broken down. It consists of a specific number of protons and variable neutrons and electrons. All of matter is made of these 118 elements, combined in various ratios and kept in different states, like solids.

The key to understanding the periodic table is in its layout. The table is comprised of seven rows (called periods), 18 columns (called groups or families). Some tables, like ours above, also include colors to help identify groups that cross rows and columns.

Of those, the two most rare metals are rhodium (Rh) and osmium (Os). This means that they are not commonly found naturally on Earth or within the universe.

How manymetals on the periodic table

Iron (Fe), platinum (Pt), molybdenum (Mo), nickel (Ni), palladium (Pd), zinc (Zn), and copper (Cu) are transition metals.

Different types of steel made add other elements to enhance properties. For example, chromium (Cr) may be added to increase steel’s hardness.

When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into. This pattern is called a period (or row) on the periodic table.

The colored areas of our table break up the elements into groups of alkali metals, alkaline earth metals, lanthanides and actinides, transition and post-transition metals, metalloids, nonmetals, halogens, and noble gases. We go in-depth on each of these groups in the questions below.

The alkali metal family includes the six elements in the first column of the periodic table, from lithium (Li) down to francium (Fr). These metals all contain one valence electron, meaning they form cations and react readily with water. These elements form the ionic bonds known as salts.

Nonmetals represent the top right of the periodic table. These elements are usually gases at room temperature and tend to form anions. Non-metals have the highest electronegativity of any of the elements, meaning they steal electrons.

The alkaline earth metals represent the second column on the periodic table. Its six elements extend from beryllium (Be) to radium (Ra). These metals are named for forming basic solutions when put into water. They tend to form cations with a positive two charge and bond ionically.

The halogen family is the main group seven on the periodic table, including fluorine down to astatine. They are all non-metals forming a singly charged anion. They represent all three states of matter.

Located right above the English name for each element, the largest letters represent its chemical abbreviation. The largest number is the element’s atomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation states, and its first ionization energy measured in kilojoules per mole.

Currently, the largest made is 118. Odd-numbered elements pose a greater challenge for isolation, as their nucleons are not as stable.
