Why do atoms with a weak electronegativity like lithium have a weak attractive force for electrons?
they have few valence electrons and aren't close to having eight valence electrons
Which element within period 2 generates greatest force of attraction between its nucleus and its valence electrons?
In period 2, the element that generates the greatest force of attraction between its nucleus and its valence electrons is fluorine. This is due to its high atomic number (9 protons), which creates a strong positive charge in the nucleus, and its relatively small atomic radius. The increased effective nuclear charge leads to a stronger attraction for the valence electrons, making fluorine highly electronegative.
What is the valence level for He?
Zero valence
Does aluminium have valence of -5?
The valence of aluminium is 3+.
The outermost electrons in an atom are called?
Valence electrons
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
The force of attraction by group 1 metals for their valence electrons is?
The force of attraction by group 1 metals for their valence electrons is weak. This is because group 1 metals have a single valence electron that is loosely held and easily lost to form positive ions.
What is the outer shell of an atom?
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.

The force attraction by group 1 metals for their valence electrons?
Group 1 metals, also known as alkali metals, have a strong force of attraction for their valence electrons due to their low ionization energy and large atomic radius. This makes it easy for them to lose their valence electrons and form positively charged ions in order to achieve a stable electron configuration.
What is an outer shell of an element?
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.Valence
What is it called when electrons in the inner energy levels block the attraction between the nucleus and the valence electrons?
It is called shielding or screening effect. Inner electrons shield the valence electrons from the positive charge of the nucleus, reducing the attractive force between them.
How many valence electrons are in an atom of aluminium?
There are 3 valence electrons in an atom of aluminium.
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
What is the valence level for He?
Zero valence
How many the valence electron of xenon?
There are no valence electrons.
Does aluminium have valence of -5?
The valence of aluminium is 3+.
