Want this question answered?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
there is no such element
When an element with few vakence electrons comes in contact with ine that has many valence electrons the reaction is more violent and vice versa.
For doing so, firstly the electronic configuration of the element is written.Then it is seen how many electrons does the element has in its valence shell.The max. no. of electrons that can be present in the valence shell is 8. So, if the element has less than 4 electrons in the valence shell, then it looses them to form stable ion and if it has more than 4 electrons, it must gain 8-no. of valence electrons to form stable ion. If the element has 4 valence electrons, then it shares them with other atoms to form compounds.
number of valence electrons
borin has more valence electrons than kernel electrons

If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
there is no such element
Neon has 0 valence electrons and so there cannot be any element with fewer valence electrons.

the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
