How many metals on the periodic table

So they have low ionization energy. I have discussed this in detailed article of Periodic table that electronegativity depends upon the size of an atom. If atomic size is less, then it has more tendency to attract the electron pair means smaller the size, more is the electronegativity. And if the atomic size is more, then it has less tendency to attract the electron pair means bigger the size, lesser is the electronegativity.

Now the elements on the left side of Periodic table have more atomic size. So they will have less electronegativity. Metals produce ringing sound when they are stuck hard. This indicates that metals are sonorous in nature. All the metals are solids at room temperature except mercury. Metals can be reshaped into thin sheets on applying sufficient pressure on it.

This property of metals is known as malleability. Metals can be drawn into thin wires. For example cable wires, thin copper wires used in electric circuit used in your laptop or phone which you are holding right now, etc …. Hardness is the ability of a material to resist wear, tear, scratching and to resist the changes in shape. Note: Sodium, potassium and lithium are soft metals which can be cut with a kitchen knife. The atoms or metals have generally 1, 2 or 3 electrons in the outermost orbit, and they lose these electrons during a chemical reaction.

Some metals get corroded easily when they are exposed to moist air or water For example: Iron. Some metals are chemically more reactive. They undergo chemical reactions by themselves or other elements and release energy. Let me tell you how this Interactive Periodic Table will help you in your studies. You can effortlessly find every single detail about the elements from this single Interactive Periodic table.

Do let me know in the comments, which part of this article you found interesting. Most of these do not occur in nature because they are so unstable but are produced in nuclear reactors and particle accelerators. Metals listed as other metals are found toward the right side of the main body of the Periodic Table.

These are sometimes called semimetals and sometimes called post-transition metals. They are typically softer than other metals and have lower melting points.

Examples of other metals include:. The types of metals on the Periodic Table can be further broken down by other properties, but these are the basic types of metals.

Alkali Metals The alkali metals can be found in the first column on the left side of the Periodic Table. The six alkali metals are: lithium sodium potassium rubidium caesium francium.

Alkaline Earth Metals The alkaline earth metals are found in column 2 on the left side of the Periodic Table. The Group 8A elements already have eight electrons in their valence shells, and have little tendency to either gain or lose electrons, and do not readily form ionic or molecular compounds.

Ionic compounds are held together in a regular array called a crystal lattice by the attractive forces between the oppositely charged cations and anions. These attractive forces are very strong, and most ionic compounds therefore have very high melting points.

Ionic compounds are typically hard, rigid, and brittle. Ionic compounds do not conduct electricity, because the ions are not free to move in the solid phase, but ionic compounds can conduct electricity when they are dissolved in water.

When nonmetals combine with other nonmetals, they tend to share electrons in covalent bonds instead of forming ions, resulting in the formation of neutral molecules. Keep in mind that since hydrogen is also a nonmetal, the combination of hydrogen with another nonmetal will also produce a covalent bond.

Molecular compounds can be gases, liquids, or low melting point solids, and comprise a wide variety of substances. See the Molecule Gallery for examples. When metals combine with each other, the bonding is usually described as metallic bonding you could've guessed that.

In this model, each metal atom donates one or more of its valence electrons to make an electron sea that surrounds all of the atoms, holding the substance together by the attraction between the metal cations and the negatively charged electrons. Since the electrons in the electron sea can move freely, metals conduct electricity very easily, unlike molecules, where the electrons are more localized.
