Do the representative elements include noble gases?

Explanation: But they do not represent the 100 or so other elements in that the Noble Gases are (i) difficult to oxidize, and (ii) difficult to reduce. And thus the Noble Gases have a limited chemistry, and as a result they tend to form compounds with ONLY the most reactive oxidants, i.e. fluorine and oxygen gas…

What do the representative elements include?

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.

Why are the elements called noble gases?

The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.

What are representative elements for class 11?

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.

What are representative metals on the periodic table?

Representative metals are members of s block and parts of p block of the table Elements of group 1, (except hydrogen) 2, 13, (except boron) tin and lead of group 14, and bismuth of group 15 are all representative metals. The metals in groups 13, 14, and 15 are not as strong metals as those in groups 1 and 2.

Why are representative elements considered representative?

Representative elements are called representative elements because they are true to the general properties expected of the group they belong to; this is because the representative elements of a group exhibit similar electron configurations, with the same number of electrons in their valence shell.

Why are the main group elements called the representative elements?

Significance of the Main Group Elements The main group elements, along with a few light transition metals, are the most abundant elements in the universe, solar system, and on Earth. For this reason, main group elements are sometimes known as representative elements.

Which of the following is the correct sequence of the noble gases in their group in the periodic table?

Which of the following is the correct sequence of the noble gases in their in the periodic table? He, Ne, Ar, Kr, Xe, Rn. Correct sequence of noble gases (down the group) is He, Ne, Ar, Kr, Xn, Rn.

Why are noble gases Noble?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

What are representative elements and why are they called so?

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.

What are representative elements give their valence shell configuration?

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

What does Representative element mean?

On the periodic table of elements, columns of elements define element groups that share many common properties. There are two sets of groups in the periodic table. The first set are Group A elements and are also known as representative elements. Representative elements are the most abundant elements on earth.
