What does K and KR have in common
Potassium (K) and Krypton (Kr) are in the same group, so they have the same number of valence electrons.
…
Potassium (K) and Krypton (Kr) are in the same group, so they have the same number of valence electrons.
Potassium is more reactive, because it has less electron shells than Krypton..
Why zinc is not a noble gas
A valence subshell is one which can react to form a bond. … So the definition of valence orbitals doesn’t depend on their quantum numbers, but on the energy required to fill them. That’s why zinc is not a noble gas – the 4p orbitals count as valence (reactive) orbitals for zinc even while the 4d don’t.
What element is in Group 10 and Period 5
Group 10, numbered by current IUPAC style, is the group of chemical elements in the periodic table that consists of nickel (Ni), palladium (Pd), platinum (Pt), and perhaps also the chemically uncharacterized darmstadtium (Ds). All are d-block transition metals.
Which element is in group 14 Period 5
TinTin is a chemical element with the symbol Sn (for Latin: stannum) and atomic number 50. It is a main group metal in group 14 of the periodic table.
What element is in group 11 Period 5
SilverSilver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver is located in Group 11 (Ib) and Period 5 of the periodic table, between copper (Period 4) and gold (Period 6), and its physical and chemical properties are intermediate between those two metals.
What are the noble gases in order

Which is the lightest gas in the world
HydrogenHydrogen is the lightest, most abundant and explosive gas on Earth. The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas. It is 220 times heavier than the lightest gas, Hydrogen.
Which is the most unreactive gas
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Why is it called a noble gas
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.

Can noble gases exist alone in nature
Since they have the maximum number of electrons that their outer shell can contain, noble gases are able to exist in nature alone because they do not need to bond with other elements to complete their shells.
What is a noble gas in Period 6
The noble gases; helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Ra) and element 118 (Uuo) occupy the rightmost group of the periodic table.
What is the 5th element of nature
The fifth element on top of earth, air, fire, and water, is space or aether. It was hard for people to believe that the stars and everything else in space were made of the other elements, so space was considered as a fifth element.
What are the 5 elements on earth
Everything in nature is made up of five basic elements: earth, water, fire, air, and space. Knowledge of the five elements allows the yogi to understand the laws of nature and to use yoga to attain greater health, power, knowledge, wisdom and happiness. This arises out of deep intuition of how the universe operates.
Why noble gases are inert in nature
Explaining the inertness of noble gases The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.
