Is Cu a representative element?

Is Cu a representative element?

– Representative elements are known to chemically active species. They undergo chemical reactions to attain the nearest noble gas configuration by losing, gaining, or sharing electrons. – The d-block elements are not considered as representative elements. – In the question, Zn, Fe, and Cu belong to the d-block.

Which element is a representative element?

In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.

What blocks are representative elements?

The elements in the periodic table are arranged into four blocks: s, p, d, and f. The elements present in s- and p-blocks are collectively known as representative elements or main group elements.

What are representative elements give their general configuration?

s and p block of elements, excluding ‘O’ group are called ‘representative elements’. Their valence configuration is ns1-2np0-5.

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.

Why are representative elements called representative elements?

The elements of “s” and “p” blocks except “d” group elements are called as representative elements because Their outer shells are not completely filled with electrons and The elements get the nearest inert gas configuration by losing or gaining or sharing of electrons. They are chemically active.

Where are the representative elements?

The representative elements on the periodic table are found on its left and right parts. They are the s block (groups 1 and 2) and p block elements (groups 13 to 18).

How do we number representative elements?

The group number of the representative elements = the number of valence electrons.

What are representative elements and why are they called so?

What kind of elements are called representative elements?

Representative elements are also known as “group A elements” or “s block and p block elements” or “main group elements”, meaning representative elements include the following groups of chemical elements;

How are transition elements different from representative elements?

Representative elements are the chemical elements in the group 1, group 2 and in the groups from 13 to 18. Transition elements are chemical elements that have unpaired d electrons at least in a stable cation that is can form. Members. Representative elements include s block and p block elements.

Which is a representative element of Group 3?

The Representative Elements 3 Chapter 18: The Representative Elements Hydrogen Electron configuration is 1s1(similar to the electron configurations of group 1A elements) Classified as a non metal Therefore it doesn’t fit into any group 4 Chapter 18: The Representative Elements Hydrogen

How are elements in the same group classified?

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
