What gases are found in the troposphere? Which of the gases among H_2, SF_6, CO_2, He, N_2, and H_2O will have the lowest/smallest effusion rate? In which state do molecules have the highest kinetic energy? What is neon's state of matter at room temperature?
What is plasma in nuclear chemistry? What gases are found in the troposphere? Give examples of noble gas configuration. What is the electron configuration for Cu? What is the chemical formula for air? Explore our homework questions and answers library ...
3.Thegases are elements, which share similar properties. These properties includebeing monoatomic, colorless, odorless, being able to conduct electricity, andhaving low chemical reactivity. Noble gases include Helium, Neon, Argon,Krypton, Xenon and Radon. These are all found in Group 18, in the...
Noble gas elementsare mostly inert, so they tend not to form compounds. So, the easiest way to find the answer to which noble gas is the heaviest or most dense is to find the element in the group with the highest atomic weight. If youlook at the noble gas element group, the last el...
So what? Atoms in a certain group (column) tend to have similar properties. So, for example, the red column on the right contains the Noble Gases (helium, neon, argon, krypton, and so on), which are relatively unreactive. The pink column on the left contains the alkali metals (lithium...
Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon. These are all found in Group 18, in the rightmost column of the periodic table. If you look at the periodic table, you will notice that these elements are the only ones, which do not have a charge. Helium has the ...
Sodium vapor HID lamps are used in street lighting. 5 Xenon Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts. Hid Past tense and a past participle of hide1. Xenon A colorless...
List the symbols of all inert gases. To which group of the periodic table do exceptionally inert gases belong? Why are they inert? What are metalloids? A) elements found in asteroids B) elements that are smaller than metals C) elements that have some properties like metals and some like no...
by gaining extra electrons or by sharing electrons with another atom. This means it is possible to predict the behavior of an atom by examining its electron configuration. Noble gases such as neon and argon are notable for their inert character: They do not take part in chemical reactions exce...
Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as isotopes of the ...
