Periodic table how many metals

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 will get the detailed information about the periodic table which will convert a newbie into pro. Do let me know in the comments, which part of this article you found interesting. Or at least comment down and let me know whether this article helped you or not. 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 six alkaline earth metals are: beryllium magnesium calcium strontium barium radium. Transition Metals The transition metals are found in the center of the main body of the Periodic Table. These semiconductors are extremely important in computers and other electronic devices.

On many periodic tables, a jagged black line see figure below along the right side of the table separates the metals from the nonmetals. The metals are to the left of the line except for hydrogen, which is a nonmetal , the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result.

Ionic bonds form when there is a transfer of electrons from one species to another, producing charged ions which attract each other very strongly by electrostatic interactions, and covalent bonds , which result when atoms share electrons to produce neutral molecules. In general, metal and nonmetals combine to form ionic compounds , while nonmetals combine with other nonmetals to form covalent compounds molecules.

Since the metals are further to the left on the periodic table, they have low ionization energies and low electron affinities , so they lose electrons relatively easily and gain them with difficulty.

They also have relatively few valence electrons, and can form ions and thereby satisfy the octet rule more easily by losing their valence electrons to form positively charged cations.

Nonmetals are further to the right on the periodic table, and have high ionization energies and high electron affinities , so they gain electrons relatively easily, and lose them with difficulty. They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.

The nonmetals gain electrons until they have the same number of electrons as the nearest noble gas Group 8A , forming negatively charged anions which have charges that are the group number minus eight.

That is, the Group 7A nonmetals form 1- charges, the Group 6A nonmetals form 2- charges, and the Group 5A metals form 3- charges.
