- The periodic table is designed so elements in the vertical columns (groups) have the most similarities in chemical and physical properties. So, Iodine is most similar to the … other non-metals in the Halogen family, such as Fluorine, Chlorine, Bromine, and Astatine.9 people found this useful.agnesium, calcium, strontium, barium and radium have similar  properties to beryllium.   All the elements in group two of the periodic table have the same  or similar p … roperties. This is because they have the same number of  electrons in their outermost shell.

Electrons In The Shells This transition element is well known for the two colors that are reddish when pure and a turquoise color when copper is oxidized. It is located in the fourth row (period) on the table of elements and is one of three elements that has one electron in its outer orbital. Potassium and chromium are the other two. Its electron configuration of 2-8-19-1 allows it to work well as a pure element and in a variety of compounds.

Transition Metals: Definition, List & Properties Chemical reactivity of the transition metals varies greatly. Some metals will react to form compounds, while others prefer to remain in their pure form. Many transition metals, like iron and titanium, will readily react with oxygen to form oxides.

Valence Electrons 1 For elements in Groups IIIA through VIIIA the outermost s and p electrons in the highest energy shell are valence electrons. 2  For transition elements the valence electrons are those in the outermost s sub-shell and in the d sub-shell of the next to outermost energy shell.

Facts about Gold 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. This is the reason why they often exhibit several common oxidation states. There are three noteworthy elements in the transition metals family. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field.

Main-group element Group 12 elements are often considered to be transition metals; however, zinc (Zn), cadmium (Cd), and mercury (Hg) share some properties of both groups, and many scientists believe they should be included in the main group.

- Technically the halogens and noble gases are nonmetals, but the nonmetal element group usually is considered to consist of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium. Properties.y Anne Marie Helmenstine, Ph.D. The nonmetals are in the minority on the periodic table, mostly pushed to the righthand side of the periodic table. Here's a look at how to locate them on the table and their common properties. Location on the Periodic Table. The nonmetals are located on the upper right side of the periodic table.

Borides The diborides (MeB2) are used most widely in engineering. The most important indicator of these materials is the change in their basic properties with temperature (see Figures 1, 2, and 3). The most important physical properties of some borides of refractory metals are shown in Table 1. A large group is formed by borides of rare-earth metals-the lantha-nides and scandium and yttrium, whose properties are similar to those of the lanthanides. The most interesting in this group are the hexaborides (MeB6).

- Therefore the number of electrons in the outer shell stays the same (2) and since this is the case, the properties are similar (for example, for non-transition metal elements such as the alkali metals, all the alkali metals have the same number of electrons in their outer shell (1) and thus they have similar properties.

The facts on chromium Chromium, a transition metal, is of intermediate atomic weight-that is, it is not considered either a heavy metal or a light metal. It is found primarily in three chemical states depending on its electrical charge.

Inner Transition Metals Inner transition elements are all metals. In modern periodic table these 30 elements are placed in two separate series at the bottom of the periodic table. The two series are called lanthanides that have atomic atomic number from 57 to 71 and actinides having atomic numbers from 89 to 103.

Group Numbers The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.Groups 3-11 are termed transition elements. Transition elements are those whose atoms have an incomplete d-subshell or whose cations have an incomplete d-subshell. Main group elements in the first two rows of the table are called typical elements.he following names for specific groups in the periodic table are in common use: 1  Group 1: alkali metals. 2  Group 2: alkaline earth metals. 3  Group 11: coinage metals (not an IUPAC approved name). 4  Group 15: pnictogens (not an IUPAC approved name).

Properties of Metals and Metal Compounds - Activity Most metals have many physical properties in common. For example, they are shiny silvery-grey solids with high melting points and boiling points, high density, good conductors of heat and electricity, malleable (easily bent or beaten into any shape) and ductile (strong enough to be drawn into wire). Metals may or may not react with oxygen, water or acid.

CONTENTS The transition metals. The transition elements are those in the middle section of the Periodic Table. All the transition elements are metals and so they have typical metallic properties-they conduct heat and electricity, they are malleable and ductile and they form positive ions when they react with non-metals.The compounds of transition metals are often coloured.he elements in the middle section of the Periodic Table are the transition elements. They're all metals with typical metallic properties eg conducting heat and electricity. They often form coloured compounds.

Transition Metals: Definition, List & Properties Elements in the lanthanide and actinide series are often considered to be inner transition metals. The transition metals are identifiable in the periodic table below as peach, the inner transition metals are dark pink and light pink in color. The d block transition metals are in columns 3-12 (often labeled 1B-10B in other versions of the periodic table). The f block inner transition metals are in the two long rows below the periodic table. Inner transition metals are often just referred to as transition metals.

IRIDIUM (REVISED) The periodic table is a chart that shows how elements are related to one another. Indium is a transition metal that is also part of the platinum family. The metals in the platinum family are also known as the noble metals. They have this name because they do not react well with other elements and compounds. They appear to be too superior to react with most other substances. In fact, iridium is the most corrosion-resistant metal known.

- Most of the transition metals can form more than one possible charge in ionic compounds. 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.he 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. The elements can be classified as metals, nonmetals, or metalloids.

Carbon group element Most transition metals, which are grouped together in the periodic table of elements, have more than one oxidation state. The oxidation state of an ion is equal to its charge, which is the number of electrons the ion has. Scandium and zinc are the only two transition metals that do not have more than one oxidation state.
