What do you mean by representative elements give example?

Representative elements are found in the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table. Representative elements include items such as S-lock and P-block.

What are the 4 representative elements?

Representative Elements List
  • Hydrogen.
  • Lithium.
  • Sodium.
  • Potassium.
  • Rubidium.
  • Caesium.
  • Francium.

What is a representative element?

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.

Which of the following is representative elements?

The elements of “s” and “p” blocks except “d” group elements are called as representative elements.

How do you identify representative elements?

Answer: The elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table are known as representative elements. S-lock and P-block elements come under the category of representative elements.

Is Silicon a representative element?

Similar procedures are important for the other representative metals. The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table.

Is Fe a representative element?

The d-block elements are not considered as representative elements. – In the question, Zn, Fe, and Cu belong to the d-block. Whereas, Sr is a p-block element.

Which block elements are known as representative elements?

So, only s and p blocks elements only are called representative elements.

Is mg a representative element?

Rubidium (Rb), Cesium (Cs), Francium (Fr), Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra).

What are representative elements for class 11?

Answer. The Representative Elements are those elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table. The Transition Metals are the elements in those Groups within the middle of the Table.

Is promethium a representative element or transition?

The period 6 inner transition metals (lanthanides) are cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu).

Is argon a representative element?

Aluminium belongs to a representative group of elements. Lanthanum belongs to lanthanoids, argon belongs to noble gas and chromium belongs to transition elements. Was this answer helpful?

Are lanthanides representative elements?

The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row …

Is platinum a representative element or transition element?

The period 6 transition metals are lanthanum (La), hafnium (Hf), tantalum (Ta), tungsten (W), rhenium (Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), and mercury (Hg).

Is Platinum Pt a representative element or a transition metal?

Platinum is a chemical element with symbol Pt and atomic number 78. Classified as a transition metal, Platinum is a solid at room temperature.

Is silicon a metal?

Silicon the semiconductor

Quartz, an abundant ingredient in sand, is made up of non-crystallized silica. Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two.

Is gold a transition metal?

Gold, symbol Au, is a transition metal and a precious metal. It is soft, dense, shiny, and the most ductile and malleable metal.

Is aluminum a transition metal?

Aluminum is the second element in the thirteenth column of the periodic table. It is classified as a post-transition metal and a “poor metal”. Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.

Is chromium a metal?

A hard, silvery metal with a blue tinge. Chromium is used to harden steel, to manufacture stainless steel (named as it won’t rust) and to produce several alloys. Chromium plating can be used to give a polished mirror finish to steel.

Who named potassium?

Humphry Davy
Potassium – the only element named after a cooking utensil. It was named in 1807 by Humphry Davy after the compound from which he isolated the metal, potash, or potassium hydroxide.

Is Neon a metal?

Non-metal is a chemical element that does not have metal’s properties. Some gases include hydrogen, helium, oxygen, nitrogen, fluorine, neon, or radon and many more. Neon is noble gas. Hence, neon is a non-metal.
