What else can I help you with?
What are the elements in Group 17-18 called?
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
In which group are the elements gases at room temperature?
There is no method to designate such properties. Only symbols with atomic number are mentioned.
Is this true except for the group 18 elements most nonmetals readily form gas?
Yes, except for the group 18 elements (noble gases), most nonmetals readily form gases due to their high electronegativity and tendency to gain electrons in chemical reactions. This allows them to exist as gases at room temperature and pressure.
What class of elements includes all of the elemnts that are gases at room temperature?
The class of elements that includes all elements that are gases at room temperature is the noble gases. These elements have full outer electron shells, making them stable and non-reactive, which allows them to exist as gases at room temperature. Examples include helium, neon, argon, and krypton.
Elements that do not combine with other elements except under specially controlled conditions belong to which group?
Noble gases are the elements that do not typically combine with other elements except under specially controlled conditions due to their stable electron configurations. They include helium, neon, argon, krypton, xenon, and radon.
What does carbon bond to?
Hydrogen
Are all elements except noble gases ions?
No, not all elements except noble gases form ions. Noble gases are considered inert because they have a complete outer electron shell, making them stable and less likely to form ions. Other elements may gain or lose electrons to form ions.
Why do atoms of all elements except noble gases not exist as single atom?
Why were you not aborted??
When elements that do not combine with other elements except under specially controlled conditions belong to the?
You think probable to noble gases.
Where are gases like hydrogen and helium most abundant?
Hydrogen and helium are the first elements produced in the universe after the big-bang.
What are the elements in Group 17-18 called?
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.
Which of the follwing insert gases is most abundant in atmosphere?
Helium is the most abundant of the Noble gases in the universe.
What are the two main gases that make up a young star?
The two main gases that make up a young star are hydrogen and helium. These elements were formed during the Big Bang and are the most abundant elements in the universe.
Which gas was the most-abundant in the secondary-atmosphere?
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
Why group7 elements are in diatomic state?
all gases are found in diatomic state. except bromine and iodine
What occurs in natures uncombined elements?
The items that occur in nature as uncombined elements are the noble gases. These gases include xenon, helium, radon, argon, neon, and krypton.
