What is neons family name?
The noble gases include: Helium He Neon Ne Argon Ar Krypton Kr Xenon Xe Radon Rn The noble gases are very stable and do not like to make compounds with other elements. There are only a bit more than one hundred compounds of noble gases.
What are general properties of the elements in the group to the right in the Modern Periodic Table?
Group 18 is the group farthest to the right on the periodic table. The elements in group 18 are also known as the noble gases. Noble gases are gases at standard temperature and pressure. Also, since they have their full complement of valence electrons they rarely make compounds with themselves or other elements.
What do the noble gases he and kr have in common?
The noble gases helium (He) and krypton (Kr) share several common characteristics, primarily their complete valence electron shells, which make them chemically inert and largely unreactive. Both gases exist in a gaseous state at room temperature and are colorless and odorless. Additionally, they are used in various applications, such as lighting and cryogenics, due to their unique properties.
Why was mendeleev unable to make any predictions about the noble gas elements?
The reason that Mendeleev didn't make any predictions about the gases was that these gases were not even discovered yet, therefore it was impossible for Mendeleev to make predictions.----Dmitri Mendeleev made his predictions on what would fill the gaps on his far from perfect periodic table. He predicted their sizes, weights, appearances, etc.I think the reason he didn't make predictions is because noble gases are not visible, and weightless.-------------------------------Mendeleev couldn't predict the noble gases' properties because their existence wasn't known, as implied above.Argon, a noble gas, was noticed twenty-five years later by John William Strutt and Sir William Ramsey (the names are not really important).It doesn't matter that the elements weren't discovered. That's the whole point of arranging the elements. To PREDICT the properties of the missing/unknown ones.
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
Why are the noble gases unreactive and what properties make them so stable compared to other elements?
Noble gases are unreactive because they have a full outer electron shell, making them stable. This full shell makes it difficult for them to gain or lose electrons, which is necessary for chemical reactions. Additionally, noble gases have low electronegativity and ionization energy, further contributing to their stability.

Why noble gasses are not active?
Noble gases are not active because of their outer shells. The outer shells of these gases are full of 8 valence electrons, which make them stable and inert.
What sentence can you make using the word noble?
The farthest right column of the periodic table contains the noble gases.
Why dont noble gases need to make compoundswith other elements?
Noble gases have completely filled orbitals (octet of electrons), they are stable and chemically inert (non-reactive).

What is a common name for the elements that make up group 18?
The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
What elements are inert gases?
Inert gases, or noble gases, make up the 18th column on the periodic table. The names of the gases (in order from top to bottom) are: helium, neon, argon, krypton, xenon, radon.
Which noble gas is the most reactive?
Neon is the least then helium is the second leastThe noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
