what is the difference between representative and transition elements?
156613
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.

Elements with a full outer shell do not form ions. The yellow section, labeled "Transition Elements" are elements that tend to lose electrons from shells other than the outermost shell and form positive ions. For example, iron (Fe) forms two different positive ions, Fe+2 (ferrous iron) and Fe+3 (ferric iron).

Why are elements in the tall columns of the periodic table called "representative elements"?

The transition metals are placed in the central part of the periodic table . The transition metals are placed between groups 2 and 3 in the periodic table.

A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals - even though they are members of the d block. ... The zinc ion has full d levels and does not meet the definition either.

The representative elements are those in which the distinguishing electron enter ans or p subshell. ... For representative elements the number of valence electrons is the same as the periodic group number, and the number needed to match the next noble-gas configuration is 8 minus the group number.

The main group elements include the active metals in the two columns on the extreme left of the periodic table and the metals, semimetals, and nonmetals in the six columns on the far right. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table.

A transition metal is one which forms one or more stable ions which have incompletely filled d orbitals. Note: The most recent IUPAC definition includes the possibility of the element itself having incomplete d orbitals as well.

The transition metals are much harder, stronger and denser than the Group I metals, which are very soft and light. ... The transition metals are much less reactive than the Group I metals. The alkali metals react with water, oxygen and halogens while the transition metals either react very slowly or do not react at all.

Sometimes included in the transition metal group are the lanthanides and actinides. They are called the "inner transition metals." The transition elements are unique in that they can have an incomplete inner subshell allowing valence electrons in a shell other than the outer shell.

Complex ions containing transition metals are usually coloured, whereas the similar ions from non-transition metals aren't. That suggests that the partly filled d orbitals must be involved in generating the colour in some way. Remember that transition metals are defined as having partly filled d orbitals.

An inner transition metal (ITM) is one of a group of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71 (lanthanides) and 89-103 (actinides). The lanthanides are very similar, and the actinides are all radioactive.

Elements having partially filled d-orbitals in ground state or in excited state, are known as transition elements. They have been placed in the centre of the Periodic Table between s-block and p-block elements. Iron is the most abundant and widely used transition metal.

The main difference between d block elements and transition elements is that d block elements have either completely or incompletely filled d orbitals whereas transition elements have incompletely filled d orbitals at least in one stable cation that they form.

Transition metals. Most metals are transition metals . They include iron and other metals used in construction, gold and other precious metals. The transition metals are placed in the central part of the periodic table .

Chemistry Portal In chemistry, the term transition metal (or transition element) has three possible definitions: The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".

Transition Metal. an element that forms one or more stable ions with a partially filled d sub-shell. D Block Element. an element where the D sub-shell is the highest energy sub-shell that is occupied. Ligand.
