What is a atom that forms a stable ion but not have an octet structure?
Helium; it has a duplet structure.
Why noble gases so stable?
Noble gases are chemically stable because they have completely filled electron orbitals. They generally have 8 valence electrons (helium has only 2) and therefore have a stable electronic configuration.
In the periodic table group 8A elements are?
These are Nobel gases, have stable elecronic configuration i.e. complete duplet (He) and octat e.g. Ne, Ar etc .
Do Helium Xenon and Neon have stable electron configurations?
Yes. Helium, Xenon, and Neon have stable electron numbers (octette rule).
What is the octet rule in terms of lewis structures?
Octet rule states that each electron wants to complete its octet ( 8 electrons in the outermost shell) or a duplet (in case of hydrogen and helium).
How are molecules of an element and a compound different?
Hydrogen symbol : H , and atomic number : 1 is an element . Whereas H2 is the hydrogen compound . The element may not be stable but molecule are always stable . When we see the molecular structure of hydrogen element , the outer most valence shell has one electron , which means hydrogen needs one more electron to fulfill its duplet . When the octate and duplet are fulfilled they are stable . In compound various element and molecules , bond to complete each others octate or duplet . Compound have certain bond . Eg electrovalent bond and covalent bond .
Is hydrogen highly stable and unreactive?
No Hydrogen is highly unstable and reactive. This is because its valency is 1 e- i.e. it will gain an electron to fulfill its duplet(it is that state when the outermost orbit has 2 e-). Deuterium is an isotope of hydrogen which is again very unstable although its duplet is fulfilled the reason for this is not known to me.
What is a atom that forms a stable ion but not have an octet structure?
Helium; it has a duplet structure.
What happen to atoms in a substance when a chemical change occur?
Then tend to become stable i.e attain an octate or duplet electron configuration.In order to do so, they form molecules by undergoing either of the 2 bondings.
Why noble gases so stable?
Noble gases are chemically stable because they have completely filled electron orbitals. They generally have 8 valence electrons (helium has only 2) and therefore have a stable electronic configuration.
Why does boron form a tripositive ion?
Boron has an electronic configuration of 1s22s22p1 (it has 5 electrons). In order to reach the stable electron configuration of a noble gas with a completely filled valence shell, boron atom has to lose 3 electrons to obtain a stable duplet structure (i.e. 2 electrons in its first electron shell). After losing 3 electrons, the boron atom forms a B3+ ion, or a so-called tripositive ion.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
Why is platinum stable?
its not stable because last orbit need to loose electron to be stable
What is a pseudo-noble gas?
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
In the periodic table group 8A elements are?
These are Nobel gases, have stable elecronic configuration i.e. complete duplet (He) and octat e.g. Ne, Ar etc .
Do Helium Xenon and Neon have stable electron configurations?
Yes. Helium, Xenon, and Neon have stable electron numbers (octette rule).
How many electrons does hydrogen have when it is stable?
Two electrons in the valence energy bands.
