In the periodic table group 8A elements are?
Group 8A elements in the periodic table are the noble gases, which include helium, neon, argon, krypton, xenon, and radon. These elements are known for their stable electron configurations and lack of reactivity.
Alkali metals lose an electron to form a stable octet. true or false?
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
Is hydride ion more stable or less stable than H-atom?
The hydride ion (H-) is more stable than the hydrogen atom (H•) because the extra electron in the hydride ion helps to stabilize the negative charge through electron-electron repulsion. Additionally, the hydride ion benefits from a full electron octet, making it more stable compared to the hydrogen atom, which has an unpaired electron.
Which family has the correct electron configuration to be stable?
The family of 'noble' (= inert) gasses in group (column) 18 of the periodic table. Their valence shell is completely filled up with s2 and p6 electrons.
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 .
How many electrons does hydrogen have when it is stable?
Two electrons in the valence energy bands.
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.
Is hydrogen atom stable and why?
Yes, a hydrogen atom is considered stable because its electron is in its lowest energy state, known as the ground state, when in its natural state. The electron and proton are held together by the electromagnetic force, forming a stable configuration.
What do you mean by octet and duplet?
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
In the periodic table group 8A elements are?
Group 8A elements in the periodic table are the noble gases, which include helium, neon, argon, krypton, xenon, and radon. These elements are known for their stable electron configurations and lack of reactivity.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
What is the formula of the ion formed when sodium achieves a stable electron configuration?
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
Why is platinum stable?
its not stable because last orbit need to loose electron to be stable
Why does neon have zero valency?
Neon has a complete outer electron shell with 8 electrons, making it stable and unreactive. Since it does not need to gain, lose, or share electrons to achieve a stable electron configuration, it is considered to have zero valency.
Alkali metals lose an electron to form a stable octet. true or false?
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
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.
