What element is nonreactive and discovered as a pure element?
Helium is a nonreactive element that was discovered as a pure element. It is a noble gas with a full outer electron shell, making it stable and unreactive with other elements.
How many valence electrons do the nob gas element contain?
noble gases all contain 8 valence electrons because they are in column 8A on the periodic chart
Which family on the periodic table does not react at all?
The noble gases family do not react with other elements since they have a full valence shell of electrons, making them stable and nonreactive.
What element has a full valence shell with electrons?
Helium. (A hydride ion has the same electronic configuration, but hydride is not an element since it has a net electric charge.)
What element would have a full valence shell on the periodic table?
The noble gases helium and neon are the only elements with completely full outer shells.
What element is nonreactive but only has 2 valence electrons?
The element that fits this description is helium. Helium is a noble gas with a full outer shell of 2 electrons, making it stable and nonreactive under normal conditions.
What element is nonreactive and discovered as a pure element?
Helium is a nonreactive element that was discovered as a pure element. It is a noble gas with a full outer electron shell, making it stable and unreactive with other elements.
Why is the the electron arrangement argon nonreactive?
Argon has a full outer shell of electrons, making it stable and nonreactive. This is because the full outer shell prevents it from easily gaining or losing electrons to form bonds with other elements. As a result, argon does not readily participate in chemical reactions.
Which shell determines the chemical property of an element?
The outermost shell of an element, called the valence shell, determines the chemical properties of the element. The number of electrons in the valence shell influences how atoms bond with other atoms to form molecules.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
How many valence electrons do the nob gas element contain?
noble gases all contain 8 valence electrons because they are in column 8A on the periodic chart
What Element have full valence shell?
Neon, Argon, Krypton, Xenon, Radon, Ununoclium.
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
What element has a complete valence electron shell?
An element with a complete valence electron shell is a noble gas. Noble gases have a full outer electron shell, making them stable and non-reactive. Examples include helium, neon, and argon.
Is the element xenon a metal or non metal?
Xenon is a nonmetal. It is a noble gas located in group 18 of the periodic table. It is known for being inert and having a full valence shell of electrons, making it stable and nonreactive.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
Which family on the periodic table does not react at all?
The noble gases family do not react with other elements since they have a full valence shell of electrons, making them stable and nonreactive.
