Why a lithium atom holds its outer electrons more strongly?
Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of?
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of increased electron-electron repulsions. As the number of electrons increases, these repulsions cause the outer electrons to be further away from the nucleus, reducing the effective attraction. This phenomenon contributes to the shielding effect and explains the reduced attraction of the nucleus for outer electrons in large atoms.
The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
Is it easier to move an electron from the outer energy level than from one closer to the nucleus?
nope.
Why do force of attraction between nucleus and electrons decrease in alkali metal as increase in size?
As alkali metals increase in size, the distance of the outermost electrons from the nucleus increases. The attraction between the electrons and the nucleus is electrostatic, and it is a fundamental property of electrostatic attractions that the attraction decreases with increasing distance between the attracting charges. Another way of describing this is that the attractive force is partially "screened" by the inner electrons between the outermost electrons and the nucleus.
Why lithium holds onto its outer most electron more strongly than sodium does?
Lithium holds onto its outermost electron more strongly than sodium due to lithium's smaller atomic size and higher nuclear charge. This results in greater attraction between the nucleus and the electron, making it harder for lithium to lose its outer electron compared to sodium.
Why are alkali metals extremely reactive?
There is only one electron in the outer most electron shell. With the lighter (less massive) alkali metals, there are less electron shells, between the outer most electron and the nucleus. Since the nucleus is positive(Protons) it more strongly holds the outer most electron. However, when going down the Alkali (Group 1) metals there are more electron shells, so the outer most electron is further away from the nucleus, and thereby less strongly held. This is evidenced by Lithium (The least massive) which only slowly effervesces in water. At the bottom of the group Francium ( The most massive) is explosive in water. NB Francium is not used in the open laboratory because it is also radio-active.
The fewer electron shells the shielding of electrons from the nucleus.?
less
What has greater pull by nucleus electron in outer shell of neon or sodium?
The nucleus of sodium has a greater pull on the electron in the outer shell compared to the nucleus of neon. This is because sodium has one less electron in its outer shell than neon, resulting in a stronger attraction between the nucleus and the remaining electron in sodium.
Why a lithium atom holds its outer electrons more strongly?
Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.
How do the inner electron shells differ from an atom's outer electron shells?
Inner electron shells are closer to the atomic nucleus and have lower energy levels compared to outer electron shells. Outer electron shells are farther from the nucleus and have higher energy levels, making them more involved in chemical reactions and bonding with other atoms.
Why florin is most electronegative?
It has a relatively high positive charge on its nucleus, a small atomic radius, only one electron shell between its nucleus and its outer electron shell, and is one electron short of a full outer shell.
How many outer shells are around the nucleus of darmstadtium?
Darmstadtium has seven electron shells around the nucleus.
Why would an increase in atomic radius make it easier to lose an outer electron?
It's because as atomic radius increases, so do the number of electron shells. The full electron shells closer to the nucleus act like a barrier or shield that reduces the pulling force exerted by the Nucleus on the outer electron. Since the nucleus's pulling force is reduced, an electron on the outer shell can escape much more easily.
What is the group that has one electron in its outer level?
alkali metal
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
