Which electron configurations are the most stable?
The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.

Explanation: Half-filled and fully filled orbitals are most stable.
Which valence electrons are most stable?
Experimental evidence shows us that atoms are most stable when they have full s and p orbitals (8 valence electrons) in their highest principle energy level.
What is the outer electron config?
0:424:16Electron Configurations (Part 9 of 12) – Inner, Outer, and Valence ElectronsYouTubeStart of suggested clipEnd of suggested clipSo the outer electrons in this case are these 4s 2 electrons. And these 4 P 5 electrons because theMoreSo the outer electrons in this case are these 4s 2 electrons. And these 4 P 5 electrons because the highest end value here is 4 so all those electrons are considered the outer electron.
How do you find the stable electron configuration?
The atoms of the Group 1 and 2 elements will lose their valence electrons in order to achieve the electron configuration of the noble gas in the previous period, and the atoms of the Groups 13-17 elements will lose, gain, or share electrons in order to achieve the electron configuration of the noble gas at the end of …
Which are the most stable atoms?
But, what about helium and other noble gases? They are considered the most stable elements in the whole periodic table.
Which is more stable d3 configuration or d5 configuration?
Since the Inner orbital (low spin) complex is more stable than the outer orbital (high spin) complex. Thus d3 configuration is more stable than d5 configuration in aqueous medium.
Is d5 or d10 more stable?
d10 orbital is more stable than d5 orbital. According to HUND'S STABILITY RULE , FULFILLED ORBITAL IS MORE STABLE THAN HALF FILLED ORBITAL AND HALF FILLED ORBITAL IS MORE STABLE THAN UNFILLED ORBITAL(which neither have half filled electron nor fullfilled electron in the orbital).
What is 1s 2s 2p 3s 3p?
1s 2s 2p 3s 3p represents the electron orbital energy levels.
Which among the following shows that an atom is stable?
A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative electrons. When the number of electrons does not equal the number of protons, the atom is ionized.
Is 1s2 2s2 2p6 stable?
Al+ has electronic configuration 1s2 2s2 2p6 3s2, and this is also unstable as Al forms Al3+ ion, so it will want to lose 2 electrons and form the same. O- has electronic configuration 1s2 2s2 2p5, which is highly unstable as it requires one more electron to form O2- ion.
What is a stable electron configuration quizlet?
What is a stable electron configuration? In a stable electron configuration, the highest occupied energy level is filled with electrons.
Which molecule is most stable?
Abstract. Polynitrogen molecules have been studied systematically at high levels of ab initio and density functional theory (DFT). Besides N(2), the thermodynamically most stable N(n)() molecules, located with the help of a newly developed energy increment system, are all based on pentazole units.
Which element is considered the most stable?
There are some 90+ elements of the periodic table that occur naturally in the Universe, but of them all, iron is the most stable.
Which is more stable d5 or p3?
d5<p3<d10<p6.
Which is more stable d5 or d10?
d10 orbital is more stable than d5 orbital. According to HUND'S STABILITY RULE , FULFILLED ORBITAL IS MORE STABLE THAN HALF FILLED ORBITAL AND HALF FILLED ORBITAL IS MORE STABLE THAN UNFILLED ORBITAL(which neither have half filled electron nor fullfilled electron in the orbital).
Which is more stable d3 or d5 configuration?
Since the Inner orbital (low spin) complex is more stable than the outer orbital (high spin) complex. Thus d3 configuration is more stable than d5 configuration in aqueous medium.
Which element has the electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 4?
According to the periodic table, this element is sulfur.
Which orbital has the highest energy 2p 3p 3d 4s?
The order of the electron orbital energy levels, starting from least to greatest, is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
Which is more stable H+ or H?
H is more stable because H+ has charge..and its is replaceable…
How do you determine if an atom is stable or unstable?
Atoms found in nature are either stable or unstable. An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy.
Which is more stable 2s2 or 2p3?
Explanation: P:1s2 2s2 2p4 it has p orbital but not half or full filled. Q:1s2 2s2 2p3 it has p orbital half filled. So, Q has more stability.
Is 1s2 2s2 2p6 3s2 stable?
Al+ has electronic configuration 1s2 2s2 2p6 3s2, and this is also unstable as Al forms Al3+ ion, so it will want to lose 2 electrons and form the same. O- has electronic configuration 1s2 2s2 2p5, which is highly unstable as it requires one more electron to form O2- ion.
What is one way in which elements can achieve stable electron configurations?
What is one way in which elements can achieve stable electron configurations? Some elements achieve stable electron configurations through the transfer of electrons between atoms. A sodium atom has one more electron than a neon atom. Removing one electron would give sodium a stable configuration.
Which of the following groups contain elements with stable electron configurations?
Stable Electron Configuration: All of the elements in group 18, also known as the noble gases, have stable electron configuration because they reach the maximum number of electrons in their shells.
Which of the following is the most stable?
CH3−CH=CH−CH2−CH3 will be the most stable because greater the number of alkyl groups attached to double bonded carbon atoms, more stable is the alkene.
Which one of the following is the most stable compound?
Therefore, Ph3C+ is most stable due to presence of three benzene rings which are resonance stabilised.
What is a stable element?
A stable atom is an atom that has enough binding energy to hold the nucleus together permanently. An unstable atom does not have enough binding energy to hold the nucleus together permanently and is called a radioactive atom.
Why is Fe the most stable element?
Well, Iron has the most stable isotope(Iron-56), it has a large half-life which means it takes a fairly large amount of time to decay into the half of what was initially there. Noble gases have a low reactivity, which means a low electronegativity and a high ionization energy.
Why is d4 more stable than d5?
d5 has more exchange energy as compared to d4 because 10 & 6 exchanges are possible in d5 & d4 respectively.
