Periodic Table of Elements Quiz 1-36

The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties. It is generally accepted that the modern periodic table was first published by Dmitri Mendeleev in 1869, although several other scientists had developed similar tables prior to this.The

periodic table is divided into 18 vertical columns, called groups, and 7 horizontal rows, called periods. The groups are numbered 1-18 from left to right, and the periods are numbered 1-7 from top to bottom. The elements in the periodic table are arranged in such a way that elements with similar chemical properties are grouped together.

For example, all of the alkali metals (Group 1) are highly reactive and form 1+ ions, and all of the noble gases (Group 18) are unreactive and form no ions.

Properties and Trends

The periodic table can be used to predict the chemical properties of elements based on their position in the table. For example, elements in the same group tend to have similar chemical properties, and elements in the same period tend to have similar atomic radii.Some

of the most important periodic trends include:*

-*Atomic radius

The atomic radius of an element is the distance from the nucleus to the outermost electron shell. Atomic radius generally increases down a group and decreases across a period.

• -*Ionization energy

  The ionization energy of an element is the energy required to remove an electron from the atom. Ionization energy generally increases across a period and decreases down a group.

-*Electronegativity

The electronegativity of an element is a measure of its ability to attract electrons. Electronegativity generally increases across a period and decreases down a group.

Reactivity and Chemical Bonding

The reactivity of an element is a measure of its tendency to undergo chemical reactions. The reactivity of elements generally increases down a group and decreases across a period.The type of chemical bond that an element forms depends on its electronegativity.

Elements with high electronegativity tend to form ionic bonds, while elements with low electronegativity tend to form covalent bonds.Some of the most common types of chemical bonds include:*

-*Ionic bonds

Ionic bonds are formed between atoms with a large difference in electronegativity. In an ionic bond, one atom donates an electron to the other atom, resulting in the formation of two oppositely charged ions.

• -*Covalent bonds

  Covalent bonds are formed between atoms with a small difference in electronegativity. In a covalent bond, the atoms share one or more pairs of electrons.

-*Metallic bonds

Metallic bonds are formed between metal atoms. In a metallic bond, the metal atoms share their valence electrons in a sea of electrons.

The elements in the periodic table are used in a wide variety of applications in science and technology. For example, the alkali metals are used in batteries, the alkaline earth metals are used in fertilizers, and the transition metals are used in catalysts.Some

of the most common applications of the elements in the periodic table include:*

-*Alkali metals

The alkali metals are used in batteries, fuel cells, and as catalysts.

• -*Alkaline earth metals

  The alkaline earth metals are used in fertilizers, cement, and glass.

-*Transition metals

The transition metals are used in catalysts, magnets, and alloys.

-*Lanthanides

The lanthanides are used in lasers, phosphors, and magnets.

-*Actinides

The actinides are used in nuclear reactors and nuclear weapons.
