The Periodic Table Today, the periodic table organizes the elements in horizontal rows, or periods, by order of increasing atomic number, which equals the number of protons in the atomic nucleus of each element. The elements are also organized in vertical columns, or groups, based on similar physical characteristics and chemical behavior. This arrangement developed side by side with atomic theory over about 200 years, and it continues to evolve as new elements are discovered.

The Periodic Table: Families and Periods Chlorine (Cl), down near the end of the period, tends to gain an electron (it’s a nonmetal). Families in the periodic table. Members of the families (vertical columns) in the periodic table have similar properties. The families are labeled at the top of the columns in one of two ways: The older method uses Roman numerals and letters. Many chemists prefer and still use this method. The newer method uses the numbers 1 through 18.

Groups : About the Group. The first column of the periodic table is the group of elements known as the Group 1 or alkali metals. This group includes lithium, sodium, potassium, rubidium, cesium, and francium.

Inner Transition Metals The two rows of elements at the bottom of the periodic table are called inner transition elements. The first row is referred to as the lanthanides the second row as the actinides. Some of the inner transition elements are synthetic not found in nature.

- In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. (See also The Periodic Table: Metals, Nonmetals, and Metalloids.) In each period (horizontal row), the atomic numbers increase from left to right.

Periodic Table of Elements Elements that lie in the same column on the periodic table (called a group) have identical valance electron configurations and consequently behave in a similar fashion chemically. For instance, all the group 18 elements are inert gases. The periodic table contains an enormous amount of important information. People familiar with how the table is put together can quickly determine a significant amount of information about an element.

The Periodic Table: Metals, Nonmetals, and Metalloids RELATED ARTICLES. Using the periodic table, you can classify the elements in many ways. One useful way is by metals, nonmetals, and metalloids. (See also The Periodic Table: Families and Periods.) Most of the elements on the periodic table are classified as metals. Metals. In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

Nightmares Sleep is divided into two types: rapid eye movement (REM) and nonrapid eye movement (non-REM). REM and non-REM sleep alternate in 90- to 100-minute cycles. Most dreaming occurs during REM sleep. Nightmares usually occur in the middle of the night or early morning, when REM sleep and dreaming are more common.

Periodic Table and Trends Review The horizontal rows on the periodic table are called periods. Most of the elements in the periodic table are classified as metals. The elements that touch the zigzag line are classified as metalloids. The elements in the far upper right corner are classified as nonmetals. Elements in the first group have one outer shell electron and are extremely reactive. They are called alkali metals. Elements in the second group have 2 outer shell electrons and are also very reactive. They are called earth alkali metals. Elements in groups 3 through 12 have many useful properties and are called transition metals. Elements in group 17 are known as “salt formers”. They are called halogens.

Alkali Metals Alkali Metals. Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and neutralizing strong acids.lkali metals, metals found in Group 1 of the periodic table. Compared to other metals they are soft and have low melting points and densities. Alkali metals are powerful reducing agents and form univalent compounds.

Periodic table A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Period. A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block. Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).

- The Alkali Metals are the first group in the periodic table. They include Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.The Alkali Metals have closer similarities between the elements than in any other group of the periodic table.For example each element shares the physical characteristics of being soft and silvery in color.. Alkali Metals constitute group 1 of the Periodic Table (Other than Hydrogen). They are named Alkali Metals because when they are mixed with water they form special solutions called alkaline solutions.

Periodic table In general, within one row (period) the elements are metals on the left, and non-metals on the right. The rows of the table are called periods; the columns are called groups. Six groups (columns) have names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases.

Facts about Gold The 38 elements in groups 3 through 12 of the periodic table are called transition metals. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat. The interesting thing about transition metals is that their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell.

Alkali metal The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).fter 1869, Dmitri Mendeleev proposed his periodic table placing lithium at the top of a group with sodium, potassium, rubidium, caesium, and thallium. Two years later, Mendeleev revised his table, placing hydrogen in group 1 above lithium, and also moving thallium to the boron group.
